This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |
