Subject: arch: cache: cp15: Add mmu_set_region_dcache_behaviour() when SYS_DCACHE_OFF is enable
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B?a=commitdiff_plain;h=ee0fbf4ef766f8d6a5a2d35906dfa2e3987f6f66;p=u-boot.git

arch: cache: cp15: Add mmu_set_region_dcache_behaviour() when SYS_DCACHE_OFF is enable

Fix following compilation issue when SYS_DCACHE_OFF is enable:
drivers/misc/scmi_agent.c:128: undefined reference to `mmu_set_region_dcache_behaviour'

when SYS_DCACHE_OFF is enable, mmu_set_region_dcache_behaviour() must be
defined.
