arm64 patch: gicv3 support

2014-04-07T22:15:12Z

This patch add gicv3 support to uboot armv8 platform. Changes for v2: - rename arm/cpu/armv8/gic.S with arm/lib/gic_64.S - move smp_kick_all_cpus() from gic.S to start.S, it would be implementation dependent. - Each core initialize it's own ReDistributor instead of master initializeing all ReDistributors. This is advised by arnab.basu . Signed-off-by: David Feng

armv8: Flush dcache before switching to EL2

2014-04-07T20:19:00Z

For ARMv8, U-boot has been running at EL3 with cache and MMU enabled. Without proper setup for EL2, cache and MMU are both disabled (out of reset). Before switching, we need to flush the dcache to make sure the data is in the main memory. Signed-off-by: York Sun Acked-by: David.Feng

armv8/cache: Flush D-cache, invalidate I-cache for relocation

2014-04-07T15:43:36Z

If D-cache is enabled, we need to flush it, and invalidate i-cache before jumping to the new location. This should be done right after relocation. Signed-off-by: York Sun CC: David Feng

kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/lib

2014-03-28T19:06:29Z

U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c. Signed-off-by: Masahiro Yamada Cc: Yuantian Tang

kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC

2014-03-07T15:59:06Z

Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

arm: Switch to -mno-unaligned-access when supported by the compiler

2014-02-26T20:19:32Z

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
