09f3ca3dd5 arm, powerpc: select SYS_GENERIC_BOARD
We have finished Generic Board conversion for ARM and PowerPC, i.e.
all the boards have been converted except OpenRISC, SuperH, SPARC,
which have not supported Generic Board framework yet.

Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro
defines in include/configs/*.h.

05e682d467 ARM: hikey: Adjust SDRAM_1_SIZE to 0x3EFFFFFF
DRAM region 0x3f000000 - 0x3fffffff is reserved for OP-TEE. Touching
0x3f000000 memory location from unsecure world causes the board
to hang.

9c71bcdc81 ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.
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.

efd7b60a81 ARM: hikey: Select DM, DM_GPIO from Kconfig
Most platforms enable these options from Kconfig rather
than the configs header file.

c9a67d2489 ARM: hikey: Use linux/sizes.h for malloc size
Use the #defines in linux/sizes for malloc size as it is
more readable.

11ac236320 ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.
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.
