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

2015-10-10T10:51:45+00:00

Introduce sparc64 architecture to buildroot. Signed-off-by: Waldemar Brodkorb Acked-by: Gustavo Zacarias Tested-by: Gustavo Zacarias Signed-off-by: Thomas Petazzoni

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

arch: tidy up binary formats config

2015-06-09T20:51:14+00:00

Instead of (black)listing architectures when deciding the binary format, we can enable the ELF format only when using an MMU and FLAT only when we're not. This mimics the logic in the Linux kernel for user binaries support. For FDPIC, we introduce a Kconfig option to enable its selection, and have blackfin select it.

arch: tidy up mmu config

2015-06-09T20:49:39+00:00

Instead of blacklisting which architectures support MMUs (mandatorily or optionally), introduce two Kconfig options that are selected by each architecture in each case. This simplifies the logic in BR2_USE_MMU. Signed-off-by: Guido Martínez Acked-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

sh64: deprecate support for this dead architecture

2015-04-25T08:32:40+00:00

As discussed on the mailinglist, this should be deprecated before removal. [Thomas: don't add to Config.in.legacy.] Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

arch: BINFMT_FLAT_SHARED is not really shared for buildroot purposes

2015-03-30T21:07:48+00:00

Although BINFMT_FLAT_SHARED is indeed a shared library format, it does not support dynamic library loading with dlopen(). So for buildroot purposes, BR2_STATIC_LIBS shouldn't be selected. As it happens, the compiler options that are added for BINFMT_FLAT_SHARED also make the compiler ignore the -static option, so we can simply force BR2_STATIC_LIBS and things work out perfectly. Therefore, remove the select of BR2_BINFMT_SUPPORTS_SHARED from BINFMT_FLAT_SHARED, which in turn makes sure that BR2_STATIC_LIBS is selected.
