Rozycki" Date: Sat, 15 Nov 2014 22:07:07 +0000 Subject: [PATCH] MIPS: Kconfig: Enable microMIPS support for Malta Add missing microMIPS support to Malta. Currently the kernel only enables support for the instruction set for the SEAD-3 board despite the fact processor features have nothing to do with the board a processor is installed in. In this case there is no way to run microMIPS software in a fully supported way under Linux on QEMU. QEMU supports the emulation of a Malta board, but does not emulate SEAD-3. Linux supports running microMIPS code on a SEAD-3 board, but hardcodes such support to off on an emulated Malta board even if the processor selected has the microMIPS instruction set implemented. Adding support for the SEAD-3 to QEMU is a major project. Flipping a bit in the kernel that shouldn't have been cleared in the first place is a trivial effort. Thus the answer is plain...
