-Subject: [PATCH 2/2] MIPS: Only set cpu_has_mmips if SYS_SUPPORTS_MICROMIPS
-
-commit 3ddc14add5e6341cf8ef4058c34c67ba7fd15317 upstream.
-
-As Jonas Gorske said in his patch:
-
- Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of
- these platforms are from before the micromips introduction, so they
- are very unlikely to implement it.
-
- Reduces an -Os compiled, uncompressed kernel image by 8KiB for
- BCM63XX.
-
-This patch taks a different approach than his, we gate the runtime
-test for microMIPS by the config symbol SYS_SUPPORTS_MICROMIPS.
