Subject: efi_loader: Use EFI_CACHELINE_SIZE in the image loader too
X-Git-Tag: v2018.07-rc1~28^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89aea436425c1b947dd812b478e9dbe29eff3e2b;p=platform%2Fkernel%2Fu-boot.git

efi_loader: Use EFI_CACHELINE_SIZE in the image loader too

We were using our EFI_CACHELINE_SIZE define only in the runtime service
code, but left the image loader to use plain CONFIG_SYS_CACHELINE_SIZE.

This patch moves EFI_CACHELINE_SIZE into efi_loader.h and converts
the image loader to use it.
