m68k: disable BR2_BINFMT_FLAT_SEP_DATA for coldfire

2016-08-22T22:08:13+00:00

BR2_BINFMT_FLAT_SEP_DATA can be used to create XIP userland and works fine for m68k. Unfortunately a lot of basic packages as pcre are not compileable because of a CPU or hardware limitation. The reason for failing are very big functions used in the libraries or application code. Typical errors are: Fatal error: Tried to convert PC relative branch to absolute jump or error: value -yyyyy out of range Add kernel patch from 4ec5542679264bc06a0356ef92f06ad7a0abe06d to make BR2_BINFMT_FLAT_ONE compiled firmware work fine. Fixes: http://autobuild.buildroot.net/results/20b/20b1586757450d6aad8583ad7a787a7ca11acef1/ http://autobuild.buildroot.net/results/d31/d311955ada1ffcd7f69e82965c8fe33eabe488cd/ Signed-off-by: Waldemar Brodkorb [Thomas: add comment in Config.in file about sep-data existing on m68k, but being disabled due to build issues with numerous packages.] Signed-off-by: Thomas Petazzoni

m68k: flat one memory region works with small kernel patch

2016-08-22T22:05:37+00:00

Greg Ungerer fixed recently a bug in the Linux kernel, which allows to use one memory region again. Signed-off-by: Waldemar Brodkorb [Thomas: cherry-picked from next to master, in order to be able to use BR2_BINFMT_FLAT_ONE by default on m68k, since BR2_BINFMT_FLAT_SEP_DATA causes too much problems.] Signed-off-by: Peter Korsgaard

arch: define dependencies for the binfmt flat formats

2016-07-05T07:48:19+00:00

The situation looks like following for elf2flt and binfmt FLAT: * Only gcc for bfin/m68k implements -msep-data (BR2_BINFMT_FLAT_SEP_DATA) and -mid-shared-library (BR2_BINFMT_FLAT_SHARED), so the corresponding options are made only visible on those architectures. * When the default of BR2_BINFMT_FLAT_ONE is used on m68k, broken binaries are produced, which mainly end up in SIGILL, so do not use it for m68k. Signed-off-by: Waldemar Brodkorb [Thomas: - also add the dependencies on m68k/bfin to BR2_BINFMT_FLAT_SHARED - rework commit log.] Signed-off-by: Thomas Petazzoni

toolchain: add coldfire support

2016-04-30T16:50:46+00:00

Add support for m68k/coldfire. A gcc patch is required to avoid gcc ICE. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

arch/m68k: re-enable the architecture

2016-03-20T14:28:44+00:00

This allows to build a m68k toolchain with uClibc. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

arch: remove BR2_ARCH_HAS_ATOMICS option

2016-02-06T10:16:00+00:00

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 Acked-by: "Yann E. MORIN"

toolchain: add sparc64 architecture support

arch: aarch64 always has a MMU

2015-07-12T16:34:42+00:00

Following the addition of AArch64 big endian, the AArch64 little endian option had lost its 'select BR2_ARCH_HAS_MMU_MANDATORY', so let's reintroduce it. Signed-off-by: Thomas Petazzoni

aarch64: add big endian(aarch64_be) support

2015-07-12T16:32:37+00:00

Add aarch64_be support. Note that CONFIG_CPU_BIG_ENDIAN should be defined in kernel config when building a big endian kernel. Signed-off-by: Zhang Jian(Bamvor) Acked-by: Gustavo Zacarias Signed-off-by: Thomas Petazzoni
