Hi Folks,
This series adds support for the first 96boards consumer edition HiKey board.
More information can be found about this board at the following link
https://www.96boards.org/products/hikey/.
This initial port adds support for: -
1) Serial
2) eMMC and sd card
3) USB
4) GPIO
It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.
Some instructions on exactly how to compile everything (l-loader,
with Arm Trusted Firmware, which then loads u-boot) is documented in the README found
in the board/hisilicon/hikey directory.
A basic SoC datasheet can be found here: -
https://github.com/96boards/documentation/blob/master/hikey/
Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf
Board schematic can be found here: -
https://github.com/96boards/documentation/blob/master/hikey/
96Boards-Hikey-Rev-A1.pdf
A rather pleasant side effect of rebasing to v2015.07-rc2 is that the two main bugs
with the v1 series (that I new about at least) are resolved. DHCP now works correctly,
and USB mass storage devices are also enumerated).
I had a quick look at migrating the gpio driver over to DT like Simon suggested.
Currently there is a bug in fdtdec_get_addr() for 64bit platforms which I ran into.
See patch from Thierry here http://permalink.gmane.org/gmane.comp.boot-loaders.u-boot/215346
Also I'm not sure on the protocol here, but the DT nodes for the gpio controller aren't
yet present in upstream Linux kernel, so I think it would be better to wait until they are,
so that u-boot and kernel DT don't diverge. Migrating over to DT at that point should
then be fairly trivial.
Changes since v1:
- Rename vendor to hisilicon not 96boards (Rob)
- Get rid of aemv8a vexpress leftover (Rob)
- Remove __weak on misc_init_r (Rob)
- Remove unnecessary LINUX_BOOT_PARAM_ADDR (Rob)
- COUNTER_FREQUENCY in decimal to avoid comment (Rob)
- Remove leftover V2M* from vexpress (Rob)
- Migrate configs/hikey.h over to use config_distro_defaults.h (Rob)
- Remove custom u-boot prompt (Rob)
- Enable icache
- Remove custom delay function, as mdelay/udelay work fine (Rob)
- Update CONFIG_SYS_LOAD_ADDR to 0x80000 (Rob)
- Use suggested macro for declaring gpio addresses (Marek)
- Zap dead Macros (Marek)
- Use calloc instead of malloc (Marek)
- Reduce PHYS_RAM by 16Mb to accomodate OPTEE in latest ATF code (Peter)
- Rebase on v2015.07-rc2 (Peter)
- Add CONFIG_NET=y so that env callbacks work (Peter)
- Add a README on how to build / flash u-boot (Simon)
kind regards,
Peter.

To: u-boot
HiKey is the first 96boards consumer edition compliant board. It features a hi6220
SoC which has eight ARM A53 cpu's.
This initial port adds support for: -
1) Serial
2) eMMC / sd card
3) USB
4) GPIO
It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.
Notes:
eMMC has been tested with basic reading of eMMC partition intto DDR. I have not
tested writing / erasing. Due to lack of clock control it won't be
running in the most performant high speed mode.
SD card slot has been tested for reading and booting kernels into DDR.
It is also currently used for saving the u-boot enviroment.
USB has been tested with ASIX networking adapter to tftpboot kernels
into DDR. On v2015.07-rc2 dhcp now works, and also usb mass storage
is enumerated correctly.
GPIO has been tested using gpio toggle GPIO4_1-3 to flash LEDs.
Basic SoC datasheet can be found here: -

+Introduction
+============
+
+HiKey is the first certified 96Boards Consumer Edition board. The board/SoC has: -
+* HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz.
+* ARM Mali 450-MP4 GPU
+* 1GB 800MHz LPDDR3 DRAM
+* 4GB eMMC Flash Storage
+* microSD
+* 802.11a/b/g/n WiFi, Bluetooth
+
+The HiKey schematic can be found here: -
+https://github.com/96boards/documentation/blob/master/hikey/96Boards-Hikey-Rev-A1.pdf
+
+A SoC datasheet can be found here: -
+https://github.com/96boards/documentation/blob/master/hikey/
+Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf
+
+Currently the u-boot port supports: -
+* USB
+* eMMC
+* SD card
+* GPIO
+
+Compile u-boot
+==============
+
+make CROSS_COMPILE=aarch64-linux-gnu- hikey_config
+make CROSS_COMPILE=aarch64-linux-gnu-
+
+ARM Trusted Firmware (ATF) & l-loader
+=====================================
+
+This u-boot port has been tested with l-loader, booting ATF, which then boots
+u-boot as the bl33.bin executable.
+
+1. Get ATF source code
+git clone https://github.com/96boards/arm-trusted-firmware.git
+
+2. Compile ATF I use the makefile here
+http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/build-tf.mak
+
+3. Get l-loader
+git clone https://github.com/96boards/l-loader.git
+
+4. Make sym links to ATF bip / fip binaries
+ln -s /home/griffinp/aarch64/bl1-hikey.bin bl1.bin
+ln -s /home/griffinp/aarch64/fip-hikey.bin fip.bin
+
+arm-linux-gnueabihf-gcc -c -o start.o start.S
+arm-linux-gnueabihf-gcc -c -o debug.o debug.S
+arm-linux-gnueabihf-ld -Bstatic -Tl-loader.lds -Ttext 0xf9800800 start.o debug.o -o loader
+arm-linux-gnueabihf-objcopy -O binary loader temp
+
+python gen_loader.py -o l-loader.bin --img_loader=temp --img_bl1=bl1.bin
+sudo bash -x generate_ptable.sh
+python gen_loader.py -o ptable.img --img_prm_ptable=prm_ptable.img --img_sec_ptable=sec_ptable.img
+
+These instructions are adapted from
+https://github.com/96boards/documentation/wiki/HiKeyUEFI
+
+FLASHING
+========
+
+1. Connect jumper J2 to go into recovery mode and flash l-loader.bin with
+ fastboot using the hisi-idt.py utility
+
+> git clone https://github.com/96boards/burn-boot.git
+> sudo python /home/griffinp/Software/hikey/burn-boot/hisi-idt.py -d /dev/ttyUSB0 --img1=/tmp/l-loader.bin
+
+2. Once LED 0 comes on solid, it should be detected as a fastboot device
+ (on some boards I've found this to be unreliable)
+
+sudo fastboot devices
+
+3. Flash the images
+wget https://builds.96boards.org/releases/hikey/nvme.img
+sudo fastboot flash ptable ptable.img
+sudo fastboot flash fastboot fip.bin
+sudo fastboot flash nvme nvme.img
+
+4. Disconnect jumper J2, and reset the board and you will now (hopefully)
+ have ATF, booting u-boot from eMMC. On 'new' boards I've had to do the
+ flashing twice in the past to avoid an ATF error.
+
+See working boot trace below: -
+
+debug EMMC boot: print init OK
+debug EMMC boot: send RST_N .
+debug EMMC boot: start eMMC boot......
+load fastboot1!
+Switch to aarch64 mode. CPU0 executes at 0xf9801000!

Can board_usb_init or usb_lowlevel_init be used here?

The enable_caches call in board_r.c should do this for you.

Just do:
#define CONFIG_PL01x_PORTS {(void *)0xf8015000}
You are probably going to want to setup multiple serial consoles
(debug + LS header). That can come later, but I've figured out how to
enable that if you are interested.

Shouldn't this be 0x80000 to avoid copying from 0x0 to 0x80000.

/dev/mmcblk0p7 doesn't look right. You mean "root=/dev/..."?

Don't you need to set these variables?
Also, don't you need to load the kernel and dtb first?

Don't you have these reversed? The first MMC device is 0 and I think
partition numbering starts at 1.

Is redundant env necessary? It seems like this was more for raw NAND
and shouldn't really be needed for MMC.

Umm I wasn't aware of those functions. It looks like usb_lowlevel_init() is used
by the host controller driver. Other host controllers like ohci / ehci and xhci call
board_usb_init() from their usb_lowlevel_init function, but not dwc2.
So I can make use of board_usb_init() if I update dwc2.c generic code to call it
from usb_lowlevel_init(). I'll do this in V3 and hopefully nobody has any objections.

Ah ok, indirectly yes, as distro_config sets CONFIG_CMD_FAT, and if that is set
config_fallbacks.h will enable CONFIG_FS_FAT.
I've removed both CONFIG_FS_FAT and CONFIG_FS_EXT4 in v3

Will remove in V3. It doesn't look like I can blame that on

I've updated this. Kernel boot time is much reduced with this and also the
icache being enabled.

Good spot, yes your right. Plus now you highlight it the comment above also needs updating.
Will fix in V3.

Yes, but I'm not sure quite what to make the default here. My personal
workflow is: -
"usb start; dhcp; tftp $kernel_addr $kernel_name; tftp $fdt_addr $fdt_name;
booti $kernel_addr - $fdt_addr"
So I could use that unless you have a better idea?

Having CONFIG_SYS_MMC_ENV_DEV 1 was deliberate, as the first device is eMMC, and
I don't have a "official" partition to save the u-boot enviroment in.
So as not to corrupt anything folks may have flashed into eMMC from the official
builds I opted to save the u-boot env to SD card which is device 1.
However that seems to have been working by luck with ENC_PART being 0, and it was
actually corrupting the partition table of the SD card. Looking more closely I think
what I should of used is
#define CONFIG_ENV_IS_IN_FAT
#define FAT_ENV_INTERFACE "mmc"
#define FAT_ENV_DEVICE_AND_PART "1:1"
#define FAT_ENV_FILE "uboot.env"
This then saves the enviroment on a fat formatted SD card with the filename
u-boot.env. This is what I plan on using for v3.
Maybe I should additionally request some space in the official eMMC parition
table and then we could switch over to using that.

README file documents it as being valid for CONFIG_ENV_IS_IN_MMC, and a bunch of boards
declare it with their CONFIG_ENV_IS_IN_MMC such as omap5_uevm.h, dra7xx_evm.h,
am335x_evm.h. Whilst using managed NAND should be more reliable, I think it
is still used in case there is a power failure whilst issuing 'saveenv'.
Anyways with moving to CONFIG_ENV_IS_IN_FAT I won't need it anymore so it will be
removed in V3.
Many thanks for your thorough reviews, you've spotted some really good stuff
that has meant boot time is now a lot quicker, and I will no longer be crapping
over peoples SD card partition table :)
kind regards,
Peter.

See this commit:
https://git.linaro.org/people/rob.herring/u-boot.git/commitdiff/f1d0aef06ae7fe09793d46589bd94fa36c45bbc0
This may be 8250 specific and require more work for pl011 driver. The
mixture of 0 and 1 based indexing makes it fun too.

Not really as everyone has their own preferences. I have some thing like this:
#define CONFIG_BOOTCOMMAND \
"while true; do " \
"mmc read ${fdt_addr_r} 0x10000 0x1000; " \
"fastboot; " \
"mmc read ${fdt_addr_r} 0x10000 0x1000; " \
"mmc read ${kernel_addr_r} 0x8000 0x8000 && " \
"bootm ${kernel_addr_r} ${kernel_addr_r} ${fdt_addr_r};" \
"done"
This relies on fastboot doing USB cable detection and it exits if no
USB connection.
USB ethernet is as good a default as any. Otherwise reading Image and
dtb from the 1st or bootable partition (the default) would be
reasonable.

Okay, but don't you have spare space in the partition with u-boot? I
have a single bootloader partition 1MB in size and the last 8? KB is
the env.

Perhaps a bunch of cut and paste. I'd guess there are many more
platforms that use MMC and don't enable redundant.

Storing in FAT probably only increases your chance of failure from
power failure. :)

No, we turn it on, on purpose, out of a certain level of paranoia (and
for ref boards like those, showing everything one could do, let $company
and their experts argue of which failure possibilities are the important
ones).

True but IMHO env in FAT is the most friendly option for a community
board. "Broke your ENV? Stick the SD card in your PC, delete .." "Here,
take a look at my env, copy this file ..." and all that.

Could use just use 'GP' or 'P'? This seems quite long as a name. Also

I think you should have:
struct peri_sc_regs {
u32 ctrl1;
u32 ctrl2;
...
};
U-Boot uses structs for I/O access.

Should be in drivers/power/pmic I think. Also use struct for reg
access. Should probably use the new PMIC uclass (we can convert it

Should define a struct for this peripheral.

This should go in a PMIC driver. Ideally most of this would happen
automatically if the voltages are in the device tree, but since you
don't have one, I suggest just moving this code into the driver.

I don't think this works yet - there is no Kconfig for it. You can put
it in your hikey.h file.

Thanks for reviewing :)
My plan regarding DT was to wait for it to land in the kernel, and then
convert
over to using it in u-boot.
I saw some of your patches converting Raspberry Pi to DM and DT which
should make migrating HiKey board fairly straight forward, as it shares the
same Synopsis IP for MMC and USB :)

OK good. For MMC I sent something with the Rockchip series but have
not applied it yet. But yes it will be easier.
I'm looking forward to trying out your series, soon.

In v3 I've added a minimal pinmux driver which I've reverse engineered
by looking at the Linux code.
Sadly the Linux pinctrl settings don't actually work for the sd card slot
and
it hangs the board. I've debugged this to not setting BIT(2) on the pull
down/up/drive registers.
I don't have any documentation on the register bit fields only the
the existing code which makes things difficult :(

Ideally yes, but unfortunately I don't have any documentation for the
register.
All I know for sure is it doesn't work without it!

I've added a clock_enable and clock_disable function in V3 and removed this

Ok I've done as you suggested and added a simple simple pmic driver
in v3. From a practical PoV this means you can now dump the pmic
regs using the pmic * commands, which might be helpful to somebody.

Yes ok. Also we wish to enable additional UARTS on the low speed connector.
In v3 in the pinmux driver I've added code for the additional UARTs.
I'm also being sent an expansion board which brings out the UARTs on the
lowspeed
connector, so I can test this :)

OK thanks for the pointer :) I'm waiting for one of Grants expansion boards
to be sent to me, so will try it out when it arrives.

Thanks for sharing your setup, I've updated the bootcmd to be the USB

Good idea, I'd not thought of that and we could most likely do that if we
wanted. However I plan on sticking with u-boot env on the sd card for the
moment
as Tom pointed out it can be a bit more user friendly for a community board.
