This driver accesses to processor's register
via __REG macros, that are removed (or are planned
to be removed) and replaced by C structures.
This patches replaces all occurrencies of __REG macros.

There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).

We need to shift only one time in each cycle in the swapping loop
for unaligned tx case. Currently two byte shift operations are
performed in each loop cycle causing zero gaps in the transmited
data, so not all data scheduled for transmition is actually
transmited.
The proper swapping in unaligned rx case is missing, so add it
as we need to put the received data into the rx buffer in the
correct byte order.

The MXC SPI driver didn't calculate the SPI clock up to
now and just used highest possible divider 512 for DATA
RATE in the control register. This results in very low
transfer rates.
The patch adds code to calculate and setup the SPI clock
frequency for transfers.

From: Stefano Babic @ 2011-01-20 8:46 UTC (permalink / raw)
To: u-boot
The patch adds suupport for the Freescale's mx35pdk board
(known as well as mx35_3stack).
The board boots from the NOR flash. Following devices
are supported:
- two ethernet devices (FEC and SMC911x on debug board)
- I2C
- PMIC (MC13892) via I2C interface
- UART
- NOR flash (64MB)
- NAND flash (2GB)
- basic access to mc9sdz60 registers via I2C interface

+Overview
+--------------
+
+mx35pdk (known als as mx35_3stack) is a development board by Freescale.
+It consists of three pluggable board:
+ - CPU module, with CPU, RAM, flash
+ - Personality board, with most interfaces (USB, Network,..)
+ - Debug board with JTAG header.
+
+The board is usually delivered with redboot. This howto explains how to boot
+a linux kernel and how to replace the original bootloader with U-Boot.
+
+The board is delivered with Redboot on the NAND flash. It is possible to
+switch the boot device with the switches SW1-SW2 on the Personality board,
+and with SW5-SW10 on the Debug board.
+
+Delivered Redboot script to start the kernel
+---------------------------------------------------
+
+In redboot the following script is stored:
+
+fis load kernel
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 rw rootfstype=jffs2 ip=dhcp fec_mac=00:04:9F:00:E7:76"
+
+Kernel is taken from flash. The image is in zImage format.
+
+Booting from NET, rootfs on NFS:
+-----------------------------------
+
+To change the script in redboot:
+
+load -r -b 0x100000 <path_to_zImage>
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/armVFP rw ip=dhcp"
+
+If the ip address is not set, you can set it with :
+
+ip_address -l <board_ip/netmask> -h <server_ip>
+
+Linux partitions:
+---------------------------
+
+As default, the board is shipped with these partition tables for NAND
+and for NOR:
+
+Creating 5 MTD partitions on "NAND 2GiB 3,3V 8-bit":
+0x00000000-0x00100000 : "nand.bootloader"
+0x00100000-0x00600000 : "nand.kernel"
+0x00600000-0x06600000 : "nand.rootfs"
+0x06600000-0x06e00000 : "nand.configure"
+0x06e00000-0x80000000 : "nand.userfs"
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+NAND partitions can be recognized enabling in kernel CONFIG_MTD_REDBOOT_PARTS.
+For this board, CONFIG_MTD_REDBOOT_DIRECTORY_BLOCK should be set to 2.
+
+However, the setup in redboot is not correct and does not use the whole flash.
+
+Better solution is to use the kernel parameter mtdparts.
+Here the resulting script to be defined in RedBoot with fconfig:
+
+load -r -b 0x100000 sbabic/mx35pdk/zImage.2.6.37
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/arm rw ip=dhcp mtdparts=mxc_nand:1m(boot),5m(linux),96m(root),8m(cfg),1938m(user);physmap-flash.0:512k(b),4m(k),30m(u),28m(r)"
+
+Flashing U-Boot
+--------------------------------
+
+There are two options: the original bootloader in NAND can be replaced with
+u-boot, or u-boot can be stored on the NOR flash without erasing
+the delivered bootloader.
+The boot storage can be select using the switches on the personality board
+(SW1-SW2) and on the DEBUG board (SW4-SW10).
+
+The second option is to be preferred if you have not a JTAG debugger.
+If something goes wrong flashing the bootloader, it is always possible to
+recover the board booting from the other device.
+
+Replacing the bootloader on the NAND
+--------------------------------------
+To replace RedBoot with U-Boot, the easy way is to do this in linux.
+Start the kernel with the suggested options. Make sure to have set the
+mtdparts exactly as described, because this matches the layout on the
+mx35pdk.
+
+You should see in your boot log the following entries for the NAND
+flash:
+
+5 cmdlinepart partitions found on MTD device mxc_nand
+Creating 5 MTD partitions on "mxc_nand":
+0x000000000000-0x000000100000 : "boot"
+0x000000100000-0x000000600000 : "linux"
+0x000000600000-0x000006600000 : "root"
+0x000006600000-0x000006e00000 : "cfg"
+0x000006e00000-0x000080000000 : "user"
+
+You can use the utilities flash_eraseall and nandwrite to put
+u-boot on the NAND. The bootloader is marked as "boot", and 1MB is
+reserved. If everything is correct, this partition is accessed as
+/dev/mtd4. However, check if it is correct with "cat /proc/mtd" and
+get the device node from the partition name:
+
+$ cat /proc/mtd | grep boot
+
+I suggest you try the utilities on a different partition to be sure
+if everything works correctly. If not, and you remove RedBoot, you have to
+reinstall it using the ATK tool as suggested by Freescale, or using a
+JTAG debugger.
+
+I report the versions of the utilities I used (they are provided with ELDK):
+
+-bash-3.2# nandwrite --version
+nandwrite $Revision: 1.32 $
+
+flash_eraseall --version
+flash_eraseall $Revision: 1.22 $
+
+nandwrite reports a warning if the file to be saved is not sector aligned.
+This should have no consequences, but I preferred to pad u-boot.bin
+to get no problem at all.
+$ dd if=/dev/zero of=zeros bs=1 count=74800
+$ cat u-boot.bin zeros > u-boot-padded.bin
+
+To erase the partition:
+$ flash_eraseall /dev/mtd4
+
+Writing u-boot:
+
+$ nandwrite /dev/mtd4 u-boot-padded.bin
+
+Now U-Boot is stored on the booting partition.
+
+To boot from NAND, you have to select the switches as follows:
+
+Personality board
+ SW2 1, 4, 5 on
+ 2, 3, 6, 7, 8 off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1
+ SW9 1
+ SW10 0
+
+
+Saving U-Boot in the NOR flash
+---------------------------------
+
+The procedure to save in the NOR flash is quite the same as to write into the NAND.
+
+Check the partition for boot in the NOR flash. Setting the mtdparts as reported,
+the boot partition should be /dev/mtd0.
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+To erase the whole partition:
+$ flash_eraseall /dev/mtd0
+
+Writing u-boot:
+dd if=u-boot.bin of=/dev/mtd0
+
+To boot from NOR, you have to select the switches as follows:
+
+Personality board
+ SW2 all off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1
+ SW9 1
+ SW10 0

If there are braces for the "if", then there shall also be braces for
the "else" ("Use braces in both branches.")

Indeed they should. Why don't you autogenerate these, then?
We have all the tools in place, use them.

Note: the following remark is a question, NOT a change request:
Would it not be possible to reduce all these terrible lists? As far
as I can tell, the list is built sequentially, with both arguments to
_MXC_BUILD_NON_GPIO_PIN() being incremented by 4 for the next
register. This begs for automatic code generation, doesn't it?

I mentioned this before: If you make board_detect() return 1 or 2,
you can combine the calls to puts() for example like that:
printf("Board: MX35 PDK %d.0 i.MX35 ", board_detect());

Eventually similar improvment could be done here. [Just a hint - feel
free to post-pone into a later patch if this affects other boards as
well.]

I just learned that I was running an old version of checkpatch, which
turned out some false positives (and my short visual inspection did
not recognize this).

0001-Add-support-for-MX35-processor.patch has style problems, please
review. If any of these errors
are false positives report them to the maintainer, see
Warnings are only related to typedef ("do not add typedef"), so I do not
know where the errors are coming from. Do you use the --no-tree option
as I usually set?

checkpatch (and generally accepted in linux, as I can see) requires that
single statements must not be surrounded by braces. checkpatch returns a
warning, explaining that braces are not needed.
I see in the past some comments requiring to remove braces, but it you
prefer to add them. IMHO it is better to follow the same codestyle as
linux, using the same tools as checkpatch. I do not know why we have two
different results from checkpatch, I try to investigate. I had prefer to
use always braces in if statement, to avoid possible errors if some code
is added, but since checkpatch complains about it I was convinced to
remove them.

See my previous comment. I would prefer to not have a different rule in
u-boot, and not go against some provided tool (we use both checkpatch)

I will check, I think I do not require anymore. NAND driver is in
mainline and does not require them. Probably I can remove them. In the
code I post now I do not use them at all, so probably I can remove them
without problems.

I do not know if it helps. The list follows exactly the description in
user manual, and, if you can see a rule for MX35_PIN_A*, it is not so
simply to find one for other pins, specially for the MXC_BUILD_GPIO_PIN.
At least, the list is at the moment coherent for all i.MX processors
(ok, ugly for all). The name of the pin cannot be generated, and it is
the name found in manual. Miore as generated, the list is sorted....

I have seen, but because __FUNCTION__is generally used, I have not
replaced the occurrencies with the suggested __func__. At least, not in
this patch. I think it is should be done in a separate patch (I will do
in next post).

I know, but I found the construct ok. checkpatch complains against using
assignment in if function, even if it is large used. Again, as we have a
tool to check patches, I will change to remove this issue.

This is exactly what you prefer, but checkpatch complains. IMHO I prefer
to fix in this patch removing braces, and do not change in previous
patches where you suggest to add braces (and then checkpatch will
complain about it).

I was unsure, it seemed to me easier to understand as it is implemented
now, becaues board_detect() is used to detect if the PMIC is installed
or not. It returns 0 or 1, and tell if the test for the PMIC was
successful.
Probably the former version of the board has no pmic at all or was not
connected to I2C. So in another part of code board_detect is used in
boolean form:
if (board_detect()) {
I thought that to combine the result makes some confusion. Probably it
is clearer to use get_board_rev() instead of board_detect() and to
extract the revision number from the returned u32:
printf("Board: MX35 PDK %d.0 i.MX35 ", (get_board_rev() >> 8) & 0xFF);

Agree, to change this I would prefer a patch for all i.MX boards at the
same time. They use at the moment the same approach I use now.

No problem, this explains the the different results. I ran checkpatch on

They are related to typedef (mmmhh...there is one regarding usage of

Did you try it?
For me, both
+ if (reg4 & 0x200)
+ pll = get_mcu_main_clk();
+ else
+ pll = decode_pll(readl(&ccm->ppctl),
+ CONFIG_MX35_HCLK_FREQ);
and
+ if (reg4 & 0x200) {
+ pll = get_mcu_main_clk();
+ } else {
+ pll = decode_pll(readl(&ccm->ppctl),
+ CONFIG_MX35_HCLK_FREQ);
+ }
generate _NO_ warnings with checkpatch.
I feel that when the "single statement" is split across several lines,
eventually even including blank lines (see yesterday's discussion
here), then braces are needed.

These are two _different_ situations.
Here we have a single statement on a single line. This needs no
braces.
In the other case, we had a single stament split over multiple lines,
and with multiple lines I want to see braces. And checkpatch appears
to be happy with braces then, too (and without as well).

It's certainly convenient the way the crime (or condition) of

From: Stefano Babic @ 2011-01-20 17:49 UTC (permalink / raw)
To: u-boot
The patch adds basic support for the Freescale's i.MX35
(arm1136 based) processor.
The patch adds also a prototype for the initialization
of the FEC(ethernet controller) to netdev.h to avoid
warnings.

Changes:
Wolfgang Denk:
- fix code styling issues reported by checkpatch
- fix missing braces (code styling)
- generates asm-offsets.h.
See arch/arm/cpu/arm1136/mx35/Makefile for rules
- drop unnedded NAND defines

From: Stefano Babic @ 2011-01-20 17:50 UTC (permalink / raw)
To: u-boot
This driver accesses to processor's register
via __REG macros, that are removed (or are planned
to be removed) and replaced by C structures.
This patches replaces all occurrencies of __REG macros.

From: Stefano Babic @ 2011-01-20 17:51 UTC (permalink / raw)
To: u-boot
There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).
The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.
This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.
The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().
Tested on Freescale mx35pdk.

From: Anatolij Gustschin <agust@denx.de>
We need to shift only one time in each cycle in the swapping loop
for unaligned tx case. Currently two byte shift operations are
performed in each loop cycle causing zero gaps in the transmited
data, so not all data scheduled for transmition is actually
transmited.
The proper swapping in unaligned rx case is missing, so add it
as we need to put the received data into the rx buffer in the
correct byte order.

The patch adds suupport for the Freescale's mx35pdk board
(known as well as mx35_3stack).
The board boots from the NOR flash. Following devices
are supported:
- two ethernet devices (FEC and SMC911x on debug board)
- I2C
- PMIC (MC13892) via I2C interface
- UART
- NOR flash (64MB)
- NAND flash (2GB)
- basic access to mc9sdz60 registers via I2C interface

+Overview
+--------------
+
+mx35pdk (known als as mx35_3stack) is a development board by Freescale.
+It consists of three pluggable board:
+ - CPU module, with CPU, RAM, flash
+ - Personality board, with most interfaces (USB, Network,..)
+ - Debug board with JTAG header.
+
+The board is usually delivered with redboot. This howto explains how to boot
+a linux kernel and how to replace the original bootloader with U-Boot.
+
+The board is delivered with Redboot on the NAND flash. It is possible to
+switch the boot device with the switches SW1-SW2 on the Personality board,
+and with SW5-SW10 on the Debug board.
+
+Delivered Redboot script to start the kernel
+---------------------------------------------------
+
+In redboot the following script is stored:
+
+fis load kernel
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 rw rootfstype=jffs2 ip=dhcp fec_mac=00:04:9F:00:E7:76"
+
+Kernel is taken from flash. The image is in zImage format.
+
+Booting from NET, rootfs on NFS:
+-----------------------------------
+
+To change the script in redboot:
+
+load -r -b 0x100000 <path_to_zImage>
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/armVFP rw ip=dhcp"
+
+If the ip address is not set, you can set it with :
+
+ip_address -l <board_ip/netmask> -h <server_ip>
+
+Linux partitions:
+---------------------------
+
+As default, the board is shipped with these partition tables for NAND
+and for NOR:
+
+Creating 5 MTD partitions on "NAND 2GiB 3,3V 8-bit":
+0x00000000-0x00100000 : "nand.bootloader"
+0x00100000-0x00600000 : "nand.kernel"
+0x00600000-0x06600000 : "nand.rootfs"
+0x06600000-0x06e00000 : "nand.configure"
+0x06e00000-0x80000000 : "nand.userfs"
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+NAND partitions can be recognized enabling in kernel CONFIG_MTD_REDBOOT_PARTS.
+For this board, CONFIG_MTD_REDBOOT_DIRECTORY_BLOCK should be set to 2.
+
+However, the setup in redboot is not correct and does not use the whole flash.
+
+Better solution is to use the kernel parameter mtdparts.
+Here the resulting script to be defined in RedBoot with fconfig:
+
+load -r -b 0x100000 sbabic/mx35pdk/zImage.2.6.37
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/arm rw ip=dhcp mtdparts=mxc_nand:1m(boot),5m(linux),96m(root),8m(cfg),1938m(user);physmap-flash.0:512k(b),4m(k),30m(u),28m(r)"
+
+Flashing U-Boot
+--------------------------------
+
+There are two options: the original bootloader in NAND can be replaced with
+u-boot, or u-boot can be stored on the NOR flash without erasing
+the delivered bootloader.
+The boot storage can be select using the switches on the personality board
+(SW1-SW2) and on the DEBUG board (SW4-SW10).
+
+The second option is to be preferred if you have not a JTAG debugger.
+If something goes wrong flashing the bootloader, it is always possible to
+recover the board booting from the other device.
+
+Replacing the bootloader on the NAND
+--------------------------------------
+To replace RedBoot with U-Boot, the easy way is to do this in linux.
+Start the kernel with the suggested options. Make sure to have set the
+mtdparts exactly as described, because this matches the layout on the
+mx35pdk.
+
+You should see in your boot log the following entries for the NAND
+flash:
+
+5 cmdlinepart partitions found on MTD device mxc_nand
+Creating 5 MTD partitions on "mxc_nand":
+0x000000000000-0x000000100000 : "boot"
+0x000000100000-0x000000600000 : "linux"
+0x000000600000-0x000006600000 : "root"
+0x000006600000-0x000006e00000 : "cfg"
+0x000006e00000-0x000080000000 : "user"
+
+You can use the utilities flash_eraseall and nandwrite to put
+u-boot on the NAND. The bootloader is marked as "boot", and 1MB is
+reserved. If everything is correct, this partition is accessed as
+/dev/mtd4. However, check if it is correct with "cat /proc/mtd" and
+get the device node from the partition name:
+
+$ cat /proc/mtd | grep boot
+
+I suggest you try the utilities on a different partition to be sure
+if everything works correctly. If not, and you remove RedBoot, you have to
+reinstall it using the ATK tool as suggested by Freescale, or using a
+JTAG debugger.
+
+I report the versions of the utilities I used (they are provided with ELDK):
+
+-bash-3.2# nandwrite --version
+nandwrite $Revision: 1.32 $
+
+flash_eraseall --version
+flash_eraseall $Revision: 1.22 $
+
+nandwrite reports a warning if the file to be saved is not sector aligned.
+This should have no consequences, but I preferred to pad u-boot.bin
+to get no problem at all.
+$ dd if=/dev/zero of=zeros bs=1 count=74800
+$ cat u-boot.bin zeros > u-boot-padded.bin
+
+To erase the partition:
+$ flash_eraseall /dev/mtd4
+
+Writing u-boot:
+
+$ nandwrite /dev/mtd4 u-boot-padded.bin
+
+Now U-Boot is stored on the booting partition.
+
+To boot from NAND, you have to select the switches as follows:
+
+Personality board
+ SW2 1, 4, 5 on
+ 2, 3, 6, 7, 8 off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1
+ SW9 1
+ SW10 0
+
+
+Saving U-Boot in the NOR flash
+---------------------------------
+
+The procedure to save in the NOR flash is quite the same as to write into the NAND.
+
+Check the partition for boot in the NOR flash. Setting the mtdparts as reported,
+the boot partition should be /dev/mtd0.
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+To erase the whole partition:
+$ flash_eraseall /dev/mtd0
+
+Writing u-boot:
+dd if=u-boot.bin of=/dev/mtd0
+
+To boot from NOR, you have to select the switches as follows:
+
+Personality board
+ SW2 all off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1
+ SW9 1
+ SW10 0

From: Stefano Babic @ 2011-01-20 18:05 UTC (permalink / raw)
To: u-boot
The patch adds suupport for the Freescale's mx35pdk board
(known as well as mx35_3stack).
The board boots from the NOR flash. Following devices
are supported:
- two ethernet devices (FEC and SMC911x on debug board)
- I2C
- PMIC (MC13892) via I2C interface
- UART
- NOR flash (64MB)
- NAND flash (2GB)
- basic access to mc9sdz60 registers via I2C interface
Signed-off-by: Stefano Babic <sbabic@denx.de>
---
Please ignore V3 of this patch : the board version was not correctly printed.
Sorry for noise.
Changes:
Wolfgang Denk:
- replace board_detect with a more correct name
- use the output of get_board_rev to print the board revision
- remove leading spaces from lowlevel_init.S

+Overview
+--------------
+
+mx35pdk (known als as mx35_3stack) is a development board by Freescale.
+It consists of three pluggable board:
+ - CPU module, with CPU, RAM, flash
+ - Personality board, with most interfaces (USB, Network,..)
+ - Debug board with JTAG header.
+
+The board is usually delivered with redboot. This howto explains how to boot
+a linux kernel and how to replace the original bootloader with U-Boot.
+
+The board is delivered with Redboot on the NAND flash. It is possible to
+switch the boot device with the switches SW1-SW2 on the Personality board,
+and with SW5-SW10 on the Debug board.
+
+Delivered Redboot script to start the kernel
+---------------------------------------------------
+
+In redboot the following script is stored:
+
+fis load kernel
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 rw rootfstype=jffs2 ip=dhcp fec_mac=00:04:9F:00:E7:76"
+
+Kernel is taken from flash. The image is in zImage format.
+
+Booting from NET, rootfs on NFS:
+-----------------------------------
+
+To change the script in redboot:
+
+load -r -b 0x100000 <path_to_zImage>
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/armVFP rw ip=dhcp"
+
+If the ip address is not set, you can set it with :
+
+ip_address -l <board_ip/netmask> -h <server_ip>
+
+Linux partitions:
+---------------------------
+
+As default, the board is shipped with these partition tables for NAND
+and for NOR:
+
+Creating 5 MTD partitions on "NAND 2GiB 3,3V 8-bit":
+0x00000000-0x00100000 : "nand.bootloader"
+0x00100000-0x00600000 : "nand.kernel"
+0x00600000-0x06600000 : "nand.rootfs"
+0x06600000-0x06e00000 : "nand.configure"
+0x06e00000-0x80000000 : "nand.userfs"
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+NAND partitions can be recognized enabling in kernel CONFIG_MTD_REDBOOT_PARTS.
+For this board, CONFIG_MTD_REDBOOT_DIRECTORY_BLOCK should be set to 2.
+
+However, the setup in redboot is not correct and does not use the whole flash.
+
+Better solution is to use the kernel parameter mtdparts.
+Here the resulting script to be defined in RedBoot with fconfig:
+
+load -r -b 0x100000 sbabic/mx35pdk/zImage.2.6.37
+exec -c "noinitrd console=ttymxc0,115200 root=/dev/nfsroot rootfstype=nfsroot nfsroot=192.168.1.1:/opt/eldk-4.2-arm/arm rw ip=dhcp mtdparts=mxc_nand:1m(boot),5m(linux),96m(root),8m(cfg),1938m(user);physmap-flash.0:512k(b),4m(k),30m(u),28m(r)"
+
+Flashing U-Boot
+--------------------------------
+
+There are two options: the original bootloader in NAND can be replaced with
+u-boot, or u-boot can be stored on the NOR flash without erasing
+the delivered bootloader.
+The boot storage can be select using the switches on the personality board
+(SW1-SW2) and on the DEBUG board (SW4-SW10).
+
+The second option is to be preferred if you have not a JTAG debugger.
+If something goes wrong flashing the bootloader, it is always possible to
+recover the board booting from the other device.
+
+Replacing the bootloader on the NAND
+--------------------------------------
+To replace RedBoot with U-Boot, the easy way is to do this in linux.
+Start the kernel with the suggested options. Make sure to have set the
+mtdparts exactly as described, because this matches the layout on the
+mx35pdk.
+
+You should see in your boot log the following entries for the NAND
+flash:
+
+5 cmdlinepart partitions found on MTD device mxc_nand
+Creating 5 MTD partitions on "mxc_nand":
+0x000000000000-0x000000100000 : "boot"
+0x000000100000-0x000000600000 : "linux"
+0x000000600000-0x000006600000 : "root"
+0x000006600000-0x000006e00000 : "cfg"
+0x000006e00000-0x000080000000 : "user"
+
+You can use the utilities flash_eraseall and nandwrite to put
+u-boot on the NAND. The bootloader is marked as "boot", and 1MB is
+reserved. If everything is correct, this partition is accessed as
+/dev/mtd4. However, check if it is correct with "cat /proc/mtd" and
+get the device node from the partition name:
+
+$ cat /proc/mtd | grep boot
+
+I suggest you try the utilities on a different partition to be sure
+if everything works correctly. If not, and you remove RedBoot, you have to
+reinstall it using the ATK tool as suggested by Freescale, or using a
+JTAG debugger.
+
+I report the versions of the utilities I used (they are provided with ELDK):
+
+-bash-3.2# nandwrite --version
+nandwrite $Revision: 1.32 $
+
+flash_eraseall --version
+flash_eraseall $Revision: 1.22 $
+
+nandwrite reports a warning if the file to be saved is not sector aligned.
+This should have no consequences, but I preferred to pad u-boot.bin
+to get no problem at all.
+$ dd if=/dev/zero of=zeros bs=1 count=74800
+$ cat u-boot.bin zeros > u-boot-padded.bin
+
+To erase the partition:
+$ flash_eraseall /dev/mtd4
+
+Writing u-boot:
+
+$ nandwrite /dev/mtd4 u-boot-padded.bin
+
+Now U-Boot is stored on the booting partition.
+
+To boot from NAND, you have to select the switches as follows:
+
+Personality board
+ SW2 1, 4, 5 on
+ 2, 3, 6, 7, 8 off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1
+ SW9 1
+ SW10 0
+
+
+Saving U-Boot in the NOR flash
+---------------------------------
+
+The procedure to save in the NOR flash is quite the same as to write into the NAND.
+
+Check the partition for boot in the NOR flash. Setting the mtdparts as reported,
+the boot partition should be /dev/mtd0.
+
+Creating 6 MTD partitions on "mxc_nor_flash.0":
+0x00000000-0x00080000 : "Bootloader"
+0x00080000-0x00480000 : "nor.Kernel"
+0x00480000-0x02280000 : "nor.userfs"
+0x02280000-0x03e80000 : "nor.rootfs"
+0x01fe0000-0x01fe3000 : "FIS directory"
+0x01fff000-0x04000000 : "Redboot config"
+
+To erase the whole partition:
+$ flash_eraseall /dev/mtd0
+
+Writing u-boot:
+dd if=u-boot.bin of=/dev/mtd0
+
+To boot from NOR, you have to select the switches as follows:
+
+Personality board
+ SW2 all off
+ SW1 all off
+
+Debug Board:
+ SW5 0
+ SW6 0
+ SW7 0
+ SW8 1

Why is this delay necessary? Why exactly 200? Is this documented
somewhere in the doc?

Rather I do not have a clear explanation. In the manual there is a hint
regarding a delay that SW must introduce after setting the RSTA bit and
before writing data into the I2DR register. Really this delay should be
very short, but I checked removing the udelay() or decreasing the value
to some uSec and it does not work.
This is the output with debugging after removing the udelay call:
i2c_read chip: 0x08 addr: 0x0007 alen: 1 len: 3
i2c_addr:chip address cycle fail(a1)
i2c_addr failed
i2c_read chip: 0x08 addr: 0x001e alen: 1 len: 3
i2c_addr:chip address cycle fail(a1)
i2c_addr failed
This happens in the i2_read() call, and it is the function where the
RSTA bit is set. I can only presume the two things are related.
I checked then with the driver provided by Freescale in the LTIB, and
also in this driver a delay is set after checking transfer is completed.
