arm: debug: add Kconfig entries for lowlevel debug

2014-10-26T21:23:12Z

We have not had a good method to debug the early boot stage such as lowlevel_init function. I guess developers generally use dedicated debuggers for that, but it is difficult in some cases. (For example, my debugger cannot connect to the ARM processor when it is in the secure state. It sometimes happens when I need to debug the early boot stage on ARM SoCs with secure extension.) The low level debug feature in Linux would be also helpful for U-boot when we are stucking in nasty problems where the console is not available yet. You have to enable CONFIG_DEBUG_LL to use this feature. For now, only 8250-compatible UART devices are supported. You can add a header file under arch/arm/include/debug/ directory to support your UART device if necessary. Signed-off-by: Masahiro Yamada

arm: Add support for semihosting for armv8 fastmodel targets.

2014-07-03T06:35:45Z

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

arm: move exception handling out of start.S files

2014-05-15T14:24:53Z

Exception handling is basically identical for all ARM targets. Factorize it out of the various start.S files and into a single vectors.S file, and adjust linker scripts accordingly. Signed-off-by: Albert ARIBAUD

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

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: make _end compiler-generated

This prevents references to _end from generating absolute relocation records. This change is binary invariant for ARM targets. Signed-off-by: Albert ARIBAUD
