X-Git-Tag: v4.14-rc1~6596^2^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b2e0a54a1296a91b800f316df7bef7d1905e4fd0;p=platform%2Fkernel%2Flinux-rpi.git

efi: Move noefi early param code out of x86 arch code

noefi param can be used for arches other than X86 later, thus move it
out of x86 platform code.
