From: Peng Fan Date: Mon, 11 May 2020 08:41:07 +0000 (+0800) Subject: armv8: cache_v8: fix mmu_set_region_dcache_behaviour X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b4b26192112bd2c225b8e424c2e2d360761cd864;p=u-boot.git armv8: cache_v8: fix mmu_set_region_dcache_behaviour The enum dcache_optoion contains a shift left 2 bits in the armv8 case already. The PMD_ATTRINDX(option) macro will perform a left shift of 2 bits. Perform a right shift so that in the end we get the correct value.
