[U-Boot] [PATCH v2 0/6] Add support for hi6220 SoC and HiKey 96boards CE board.

[Peter Griffin]

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: -

Board schematic can be found here: -

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.
