* ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.Peter Griffin2015-09-28-0/+50
| | | | | | | | | | | | | | | | | | | Use DM for the pl01x serial driver on hikey. Also allow UART0 or UART3 to be chosen via Kconfig. By default we now output to UART3 as the latest version of ATF outputs to this UART. Also UART3 comes out on the LS connector, as opposed to UART0 which goes to a unpopulated header. As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and call the pinmux configuration code for the UART. Before we were relying on ATF having already configured the pin configuration. NB: Upstream Linux kernel doesn't yet support UART3, so serial console will still be output on UART0 when booting a upstream kernel.

* ARM: hikey: Remove resetting gd->flags in board_init()Peter Griffin2015-09-28-2/+0
| | | | | | | | | | | | | This causes exceptions and other strange behaviour when enabling CONFIG_SYS_MALLOC_F_LEN which is required to migrate the serial driver over to DM_SERIAL. As GD_FLG_FULL_MALLOC_INIT flag gets reset, after relocation we don't end up using the full malloc which ultimately ends up causing a synchronus abort.

* ARM: hikey: Add ATF makefile referenced by READMEPeter Griffin2015-09-28-0/+42
| | | | | | | Rather than relying on an external URL in the README include the Makefile in the hikey directory. Signed-off-by: Peter Griffin <peter.griffin@linaro.org>
* ARM: hikey: Update README with various correctionsPeter Griffin2015-09-28-50/+147
| | | | | | | | The README had a few mistakes, and one of the URL's had changed. Also update the boot log with the latest boot trace from ATF, which now includes the mcuimage.bin. Signed-off-by: Peter Griffin <peter.griffin@linaro.org>

* ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.Peter Griffin2015-08-12-0/+379
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 into 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 configured to save the u-boot environment to the SD card. 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 are correctly enumerated. GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.
