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"

arch: add support for mips32r6 and mips64r6 variants

2015-10-12T19:33:56+00:00

- Add support for mips32r6 and mips64r6 target architecture variants - Disable unsupported gcc versions - Disable unsupported binutils versions - Disable unsupported external toolchains - Disable unsuported C libraries - Add a hook in order to make glibc compile for MIPS R6. [Thomas: slightly tweak the glibc hack explanation, to make it hopefully clearer.] Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

arch/mips: remove deprecated mips1/2/3/4 support

2014-12-01T19:06:32+00:00

Remove the support for generating mips1/2/3/4 code since it has been deprecated for more than a year now. Also remove the unnecessary kludges in packages for it. Signed-off-by: Gustavo Zacarias Acked-by: Vicente Olivert Riera Signed-off-by: Peter Korsgaard

Disable o32 ABI for MIPS64 architectures

2014-03-28T11:51:46+00:00

Building o32 ELF files for MIPS64 is an exotic configuration that nobody should be using. If o32 is required, then is better if it's built for MIPS 32-bit cores so only 32-bit instructions will be used leading to a more efficient o32 usage.

deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx

2014-01-10T14:03:53+00:00

In order to keep better track of when a feature got deprecated, and hence when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is introduced. These symbols are automatically selected when BR2_DEPRECATED is selected, and thus are transparent to the user. A deprecated feature will no longer depend on BR2_DEPRECATED directly, but rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does not yet exist, it has to be created in Config.in. When removing a deprecated feature, one should also check whether this was the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which case the latter can be removed from Config.in. A followup patch will make sure the overview is added to the list of deprecated features in the manual, so that a buildroot core developer can easily determine which features to remove in a given development cycle.

Disable MIPS64 ISAs for MIPS32 targets

2014-01-03T19:43:25+00:00

Currently you can select MIPS64 ISAs, like mips64 and mips64r2, for MIPS32 targets. This is incorrect, so we disable the possibility to do that. Reviewed-by: Markos Chandras Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

Mark MIPS I, II, III and IV as deprecated

arch/Config.in: introduce BR2_KERNEL_64_USERLAND_32 symbol

2013-10-30T21:59:03+00:00

On some architectures one can be running a 64-bit kernel with a 32-bit userland. Such is the case for sparc64 (unsupported) for example and mips64 with n32 ABI. Some tools that interface directly with the kernel need to be built specially for this, so introduce this symbol to tweak their build in one central kludge to be future-proof. Example: bug #6602.
