[U-Boot] [PATCH v4 0/9] Add support for hi6220 SoC and HiKey 96boards CE board.

[Peter Griffin]

Hi Albert / Tom,

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: -

Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf

Board schematic can be found here: -

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).

The plan is once basic support is merged to u-boot, and upstream Linux kernel has DT
which supports GPIO, UART and MMC, we can migrate this u-boot port over to using DT
for configuration.

Changes since v3:
- Update to use config_distro_bootcmd.h (Sjoerd)
- Remove CONFIG_BOOTDELAY (Sjoerd)

Changes since v2:
- errno.h should go above malloc.h (Simon)
- drop #ifdef CONFIG_DM_GPIO and add TODO (Simon)
- remove gd->flags = 0; (Simon)
- Remove icache_enable() (Simon / Rob)

- Added a pinmux driver for hi6220 (Simon)
- Added a pmic driver for hi6553 (Simon)
- Convert to structs for register I/O (Simon)
- Remove () around simple constants (Simon)

- Update default bootcmd (Rob)
- user kernel_addr_r etc in default env (Rob)
- Various typo's (Rob)
- use board_usb_init() to configure phy/clocks (Rob)
- Remove some more unnecessary CONFIG_FS* options (Rob)
- Update default kernel load address (Rob)
- Update default kernel cmdline (Rob)

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.
