[U-Boot] [PATCH v8 0/5] 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.
u-boot could be running at EL1 or EL2.

Changes for v7:
  - Integrate SMC91111 patch of sharma bhupesh.
  - remove v8_outer_cache* which is not need currently.
  - Change license tag.
  - Mov crt0.S/relocate.S/interrupts.c to arm/lib and
    rename them with _64 suffix.
  - Make el3/el2 initializing process of start.S as
    two separate routines. It could be easier to be
    replaced with processor specific codes.
  - Remove exception stack save and restore routine,
    it is unnecessary now.

Changes for v6:
  - Check the patches with checkpatch.pl and get rid of
    almost all warnings. There are a few warnings still,
    but I think it should be that.
  - change printf format in cmd_pxe.c, use %zd indtead
    of %ld to format size_t type variable.
  - add macro PGTABLE_SIZE to identify tlb table size.

Changes for v5:
  - Make modification to inappropriate licensed file
    and bugs according to ScottWood's advice.
    Thanks Scott for his checking to these patches.
  - Enable u-boot's running at EL1.
  - Get rid of compiling warnings originated from cmd_pxe.c.

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

Changes for v3:
  - merge arm64 to arm architecture.

David Feng (5):
  core support of arm64
  board support of vexpress_aemv8a
  generic board patch of manual reloc and zero gd_t
  64bit initrd start address support
  remove compiling warnings
