* arch: remove BR2_ARCH_HAS_ATOMICS optionGravatar Thomas Petazzoni2016-02-061-3/+0
| | | | | | | | Now that BR2_ARCH_HAS_ATOMICS is no longer used anywhere, we can remove it from arch/Config.in*, as well as from the documentation. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

* Fix microblize little endian toolchainGravatar Jan Drazil2014-03-201-1/+2
| | | | | | | | | | | | Buildroot toolchain creates big endian binaries instead of little endian ones for microblaze architecture. The reason is wrong BR2_ARCH string. KERNEL_ARCH must contain microblaze in both cases.

* arch: improve definition of gcc mtune, mcpu, etc.Gravatar Thomas Petazzoni2012-11-151-0/+10
As suggested by Yann E. Morin, there is a better way than our current big Config.in.common to define the gcc mtune, mcpu, march, etc. values. We can split the setting of those values in each architecture file, which makes a lot more sense. Therefore, the Config.in file now creates empty kconfig variables BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH, BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those variables are set by the individual Config.in.<arch> files. This is possible because such files are now only conditionally included depending on the top-level architecture that has been selected.
