Subject: efi_loader: update runtime services table crc32
X-Git-Tag: v2018.09-rc3~33^2~6
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a39f39cdd8be5cd3e7a8b696a463b621e3d827e0;p=oweals%2Fu-boot.git

efi_loader: update runtime services table crc32

The crc32 of the runtime services table must be updated after detaching.

efi_update_table_header_crc32() must be __efi_runtime. So move it to
efi_runtime.c
