[U-Boot] [PATCH v5 0/4] arm64 patch

[fenghua at phytium.com.cn]

From: David Feng <fenghua at phytium.com.cn>

The porting has been merged with arm architecture.
Most architecture codes are placed in arch/arm/cpu/armv8 directory.
Generic board is also supported after a few bugs are fixed.

Changes for v4:
  - fix the generic board_f.c, remove zero_global_data from init_sequence_f array
    and move it to board_init_f() function with CONFIG_X86 switch. The previous
    fixup is inaccurate.
  - Replace __ARMEB__ with __AARCH64EB__ in byteorder.h and unaligned.h,
    gcc for aarch64 use __AARCH64EB__ and __AARCH64EL__ to identify endian.
  - Some modification to README.armv8

David Feng (4):
  core support of arm64
  board support of arm64
  generic board patch of manual reloc and zero gd_t
  64bit initrd start address support
