* m68k: remove BR2_GCC_TARGET_ARCHWaldemar Brodkorb2016-06-071-4/+0
| | | | | | | | | | Setting BR2_GCC_TARGET_ARCH is possible, but breaks external toolchain users. m68k/cf defconfigs just working without it.

* toolchain: add coldfire supportWaldemar Brodkorb2016-04-301-0/+20
| | | | | | | | Add support for m68k/coldfire. A gcc patch is required to avoid gcc ICE. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* arch/m68k: re-enable the architectureWaldemar Brodkorb2016-03-201-6/+14
| | | | | | | This allows to build a m68k toolchain with uClibc. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* arch: remove BR2_ARCH_HAS_ATOMICS optionThomas 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>
* arch/m68k: get rid of BR2_GCC_TARGET_TUNEThomas Petazzoni2014-11-071-8/+0
| | | | | | | | | | On m68k, we are passing the exact same values of BR2_GCC_TARGET_ARCH and BR2_GCC_TARGET_TUNE, which is redundant. Therefore, this commit removes the usage of BR2_GCC_TARGET_TUNE on m68k. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Reviewed-by: "Yann E.

* arch: improve definition of gcc mtune, mcpu, etc.Thomas Petazzoni2012-11-151-0/+21
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.
