Subject: MIPS: introduce CPU_R4K_CACHE_TLB
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=62cedc4fde2d15b08e4502aa3fb2d9d798f3ccd8;p=openwrt%2Fstaging%2Fblogic.git

MIPS: introduce CPU_R4K_CACHE_TLB

R4K-style CPUs having common code to support their caches and tlb have this
boolean defined by default. Allows us to remove some lines in
arch/mips/mm/Makefile.
