2014-10-28gic: fixed compilation error in GICv2 wait for interrupt macroYehuda Yitschak

2014-10-26arm: debug: adjust for U-BootMasahiro Yamada
Because CONFIG_MMU is never defined in U-Boot, the non-MMU code in debug.S is always used. Unfortunately, the number of arguments of the addruart macro in Linux is different between MMU and non-MMU. This causes a build error when importing some debug macros using the third argument. (For ex. arch/arm/include/debug/exynos.S) Pass the third argument to the non-MMU addruart to avoid such a problem.

2014-10-26arm: debug: add Kconfig entries for lowlevel debugMasahiro Yamada
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 <yamada.m@jp.panasonic.com>

2014-10-23mips: enable CONFIG_USE_PRIVATE_LIBGCC by defaultMasahiro Yamada
Without the private libgcc, we need a full multilib toolchain with different libgcc or multiple toolchains to build all BE/LE and hard-float/soft-float variants of MIPS boards. That is not feasible. This commit allows us to build all the MIPS boards with a single kernel.org toolchain: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz This change sounds reasonable for most users. If necessary, you can disable this option via "make menuconfig" or friends. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-10-23kconfig: move CONFIG_USE_PRIVATE_LIBGCC to KconfigMasahiro Yamada
The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86. Those architectures should "select" HAVE_PRIVATE_LIBGCC and CONFIG_USE_PRIVATE_LIBGCC should depend on it. Currently, this option is enabled on Tegra boards and x86 architecture. Move the definition from header files to Kconfig.

2014-10-23x86: set CONFIG_USE_PRIVATE_LIBGCC to yMasahiro Yamada
The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC to a boolean macro so we can move it to Kconfig. In the current implementation, there are two forms of syntax for this macro: - CONFIG_USE_PRIVATE_LIBGCC=y - CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc The latter is only used by x86 architecture. With a little bit refactoring, it can be converted to the former.
