Well, the way I look at it we have two answers: 1) In general, any sane for your architecture gcc 4.x or later should work. I'm not going to test every possible combination here but maintainers (who might have less visible needs like hey, our product uses toolchain X, so I need to use it) may also say their board needs to work with toolchain X. 2) To me, ELDK current release, current kernel.org toolchains and current commodity distro (Debian, Fedora, SuSE, etc) toolchains should work too. I personally use ELDK 5.6 or PowerPC and MIPS, kernel.org for most everything else and Debian 8 arm-none-eabi (gcc 4.8.x) as that does both armv7 and armv7m, and then Debian/Unstable gcc 5.x for x86/aarch64/arm/sandbox/powerpc. -- Tom
