From: David Feng fenghua@phytium.com.cn
Changes for v15: - modify boot process, u-boot will run at the highest exception level until it prepare jump to OS. - Fix a few bugs in cache.S.These bug is reported by York Sun yorksun@freescale.com and Scott Wood scottwood@freescale.com. - when booting, slaves will wait on WFI, master wakeup slaves by SGI interrupt. - add generic_timer.c to utilize the newest timer architecture. - add gic.S to support gic initialization and interrupt operations, currently only support GICv2.
Changes for v14: - Merge rela relocation patches from Scott Wood scottwood@freescale.com. - Remove all CONFIG_NEED_MANUAL_RELOC and other fixups due to manual relocation. With rela relocation patches them are not needed. - Fix the bug of MEMORY_ATTRIBUTES definition due to assembler. That need put brackets around (MT_NORMAL*8). Otherwise the result is wrong.This bug is reported by York Sun yorksun@freescale.com. - -msoft-float is not supported by aarch64-gcc, make a test though $(call cc-option,-msoft-float). - Adjust the virtual address space to 42 bits. - Filter armv8 boards from LIST_arm in MAKEALL. - remove gpio.h in asm/arch-armv8/ and move mmu.h to asm/armv8/ directory. - remove vexpress64.dts from this patch, it could be accessed from linux kernel.
Changes for v13: - fix the bug of board_r.c and arm/lib/board.c due to CONFIG_NEED_MANUAL_RELOC. adjust initr_serial() in board_r.c to the first entry of init_sequence_r[] and relocate serial_initialize() in arm/lib/board.c, routines of serial_device should be relocated firstly by serial_initialize(), so that printf access the correct puts function, otherwise uninitialized serial_current will be selected as the output device. - fix the bug of dcache_enable(). after mmu_setup the sctrl register value should be fetched again because it has been modifed by mmu_seup() function. This bug is reported by York Sun yorksun@freescale.com. - add macro branch_if_slave to macro.h, it choose processor with all zero affinity value as the master and is used in start.S.
Changes for v12: - custom the patches to new format boards.cfg.
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.
David Feng (10): fdt_support: 64bit initrd start address support cmd_pxe: remove compiling warnings add weak entry definition arm64: Add tool to statically apply RELA relocations arm64: Turn u-boot.bin back into an ELF file after relocate-rela arm64: Make checkarmreloc accept arm64 relocations arm64: core support arm64: generic board support arm64: board support of vexpress_aemv8a arm64: MAKEALL, filter armv8 boards from LIST_arm
