[U-Boot] [RESEND PATCH v5 2/6] cgtqmx6eval: Use SPI NOR to store the environment

[Otavio Salvador]

Congatec boards boot from SPI NOR, so it makes more sense to use
SPI NOR to store the environment variables.

[U-Boot] [RESEND PATCH v5 3/6] cgtqmx6eval: Add fastboot support

[Otavio Salvador]

Tested basic fastboot commands, such as:

On the U-boot prompt:

=> fastboot 0

On the host PC:

$ fastboot getvar bootloader-version -i 0x0525
bootloader-version: U-Boot 2015.10-rc2-09654-g8f41d27
finished. total time: 0.000s

$ fastboot reboot -i 0x0525 --> board reboots fine.

-U-Boot for the Congatec Conga-QEVAl Evaluation Carrier board with

+U-Boot for the Congatec QMX6 boards
 
 This file contains information for the port of U-Boot to the Congatec
-Conga-QEVAl Evaluation Carrier board with qmx6 quad module.
+QMX6 boards.
 
-1. Boot source, boot from SD card
+1. Building U-boot
+------------------
+
+- Build U-boot for Congatec QMX6 boards:
+
+$ make mrproper
+$ make cgtqmx6eval_defconfig
+$ make
+
+This will generate the following binaries:
+
+- SPL
+- u-boot.img
+
+2. Flashing U-boot in the SPI NOR
 ---------------------------------
 
-By default, the Congatec board can boot only from the SPI-NOR.
-But, with the u-boot version provided with the board you can write boot
-registers to force the board to reboot and boot from the SD slot. If
-"bmode" command is not available from your pre-installed u-boot, these
-instruction will produce the same effect:
+Copy SPL and u-boot.img to the exported TFTP directory of the
+host PC (/tftpboot , for example).
+
+=> sf probe
+
+=> tftp 0x12000000 SPL
+
+=> sf erase 0x0 0x10000
+
+=> sf write 0x12000000 0x400 0x100
+
+=> tftp 0x12000000 u-boot.img
+
+=> sf erase 0x10000 0x70000
+
+=> sf write 0x12000000 0x10000 0x70000
+
+Reboot the board and the new U-boot should come up.
+
+3. Booting from the SD card
+---------------------------
+
+- Flash the SPL image into the SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Insert the SD card into the big slot.
+
+The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
+the board from SPI first.
 
-conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850
-conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000
-conga-QMX6 U-Boot > reset
-resetting ...
+It is also possible to boot from the SD card slot by using the 'bmode'
+command:
 
-The the board will reboot and, if you have written your SD correctly
-the board will use u-boot that live into the SD
+=> bmode esdhc4
 
-To copy the resulting u-boot.imx to the SD card:
+And then the U-boot from the big slot will boot.
 
- dd if=u-boot.imx of=/dev/xxx bs=512 seek=2
+Note: If the "bmode" command is not available from your pre-installed U-boot,
+these instruction will produce the same effect:
 
-Note: Replace xxx with the device representing the SD card in your system.

I have asked to move the spi_nor int stuff on #ifdef CONFIG_SPI_MXC in
previous patch any response on that?

I missed this; but any other request so we can finally get this merged?

No other comments please add the driver #ifdef on spi_nor init code
and send the next version patch.

thanks!

Is this really needed?

Given that:

- The boot medium of this board is SPI NOR
- We want CONFIG_SPI_MXC to be always selected
- We don't want to polute the code with ifdef's

I thinks the code is fine as is.

Regards,

Fabio Estevam

Since it's u-boot, size is main constraint ie the main reason to use
ifdef and also this initialization code must be part of driver probe
instead of board file, once the driver moved to dm then will move this
as well so to indicate that this could be a driver code better to use
the driver config in #ifdef.

See this
$ grep -R CONFIG_MXC_SPI board/

And use setup_spi instead of setup_spinor

In this board CONFIG_SPI_MXC will always be selected, so size
constraint does not apply here.

What is the reason for that?

I'm saying about setup_spinor init code see  "grep -R CONFIG_MXC_SPI
board/ " how they defined.

Because this is spi controller setup not the spi_nor - please see the
boards which uses CONFIG_MXC_SPI

$ grep -R CONFIG_MXC_SPI board/

thanks!
