Subject: x86: Remove calculate_relocation_address()
X-Git-Tag: v2015.10-rc3~92^2~45
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c17ca6b5cd7158b63a78c4944c732c49dce8454f;p=platform%2Fkernel%2Fu-boot.git

x86: Remove calculate_relocation_address()

Now that we have generic routine to calculate relocation address,
remove the x86 specific one which is now only used by coreboot.
