Changes for v11: - Replace CONFIG_ARMV8 with CONFIG_ARM64. Currently, it's hard to distinguish what is armv8 specific and what is aarch64 specific, so we use CONFIG_ARM64 only, no CONFIG_ARMV8 used. - rename README.armv8 with README.arm64 and make some modification.
Changes for v10: - add weak definition to include/linux/linkage.h and make setup_el2/setup_el3/lowlevel_init weak routines, so them can be easily overridden by processor specific code. - modify s-o-f of 0002-board-support-of-vexpress_aemv8a which use wrong mail address of Bhupesh Sharma.
Changes for v9: - add Signed-off-by information to patch "board support of vexpress_aemv8a" which SMC91111 support is integrated from Sharma Bhupesh's patch. - adjust pt_regs struct and add exception state preservation in exception.S.
Changes for v8: - 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. - simplify __weak function declaration.
Changes for v7: - 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 v6: - 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 v5: - 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 v4: - merge arm64 to arm architecture.
