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 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.
