toolchain/crostool-NG: mark as deprecated

2013-05-07T21:01:09Z

For the following reasons: - it used to be broken without anyone noticing for a long time, - it is still not fully integrated within the Buildroot set of options, - it has not gained much traction (not even I use it), - I've always argued that sustained development should use an external toolchain, and not rely on building one with Buildroot, - I did not submit any of the enhancements requested during the last developpers' day in Brussels, - I have neither the incentive nor the time to maintain and enhance it, it is time to deprecate the crosstool-NG backend for the 2013.05 release. Then, it will be entirely removed early in the 2013.08 cycle, to let some time for those that rely on it to voice their opinions. ;-) Signed-off-by: "Yann E.

toolchain/gcc: Enable --with-float for powerpc

2013-05-06T10:29:34Z

Commit 8d929f4b ("toolchain/gcc: Only enable --with-float when it makes sense") restricted the --with-float use to only MIPS, ARM and SPARC, while it seems that powerpc needs it as well. Fixes the qemu_ppc_virtex_ml507_defconfig build. Signed-off-by: Maxime Ripard Signed-off-by: Peter Korsgaard

arch: toolchain: Introduce target CPU revision.

2013-05-05T20:49:50Z

Adds the possibility to have a free-form CPU revision string and append it to the target CPU. Only Blackfin actually uses this option. Signed-off-by: Sonic Zhang Acked-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

arch: toolchain: Introduce binary formats BINFMT_*.

2013-05-05T20:46:37Z

Just introduce the symbol and options in arch generic Config.in. Append FLAT format link flags to external toolchain wrapper. Signed-off-by: Sonic Zhang Acked-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

kernel-headers: Add support for ARC kernel headers

2013-05-04T21:24:02Z

Also make sure that older kernels are not selected for ARC. Signed-off-by: Mischa Jonker Signed-off-by: Peter Korsgaard

toolchain/toolchain-buildroot: Disable NPTL for ARC

2013-05-04T21:21:31Z

NPTL is not yet supported for ARC. Signed-off-by: Mischa Jonker Signed-off-by: Peter Korsgaard

toolchain/gcc: Only enable --with-float when it makes sense

2013-05-04T21:21:31Z

According to gcc/config.gcc, only ARM, MIPS and SPARC have the "--with-float" option when configuring gcc. [Peter: sort list] Signed-off-by: Mischa Jonker Signed-off-by: Peter Korsgaard

arc: Make sure that libgcc doesn't get included when it doesn't exist yet

2013-05-04T21:21:31Z

For ARC, libgcc is always included, even when -nostdlib is given. This is related to some small pieces of code that are not always generated by the compiler; a call to libgcc is used in those cases instead. During the initial stages of building the toolchain, this is a problem, as libgcc does not exist yet. The ARC compiler supports -really-nostdlib to override the default behavior.
