* arch: toolchain: Introduce binary format FLAT types.Gravatar Sonic Zhang2013-05-051-0/+26
| | | | | | | | | Just introduce the symbol and options in arch generic Config.in. Add FLAT types specific compiling flags into package makefile.

* arch: toolchain: Introduce target CPU revision.Gravatar Sonic Zhang2013-05-051-0/+3
| | | | | | | | | Adds the possibility to have a free-form CPU revision string and append it to the target CPU. Only Blackfin actually uses this option.

* xtensa: add support for the Xtensa architectureGravatar Chris Zankel2012-11-151-0/+11
| | | | | | | | | | | | | The Xtensa architecture had been removed because it required special handling and depended on additional directories and files that became obsolete over time. This change is more aligned to other architectures. [Thomas: rebased on top of the "arch: improve definition of gcc mtune, mcpu, etc." patch].

* arch: improve definition of gcc mtune, mcpu, etc.Gravatar Thomas Petazzoni2012-11-151-4/+55
| | | | | | | | | | | | | | | | | | 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.

* Split target/Config.in.arch into multiple Config.in.* in arch/Gravatar Thomas Petazzoni2012-11-041-0/+161
target/Config.in.arch had become too long, and we want to remove the target/ directory. So let's move it to arch/ and split it this way: * An initial Config.in that lists the top-level architecture, and sources the arch-specific Config.in.<arch> files, as well as Config.in.common (see below) * One Config.in.<arch> per architecture, listing the CPU families, ABI choices, etc. * One Config.in.common that defines the gcc mtune, march, mcpu values and other hidden options.
