From: Peter Tyser Date: Mon, 21 Sep 2009 16:20:36 +0000 (-0500) Subject: Conditionally perform common relocation fixups X-Git-Tag: v2009.11-rc1~61^2~4 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=521af04d853361b49344b61892eb0618f9f713c5;p=oweals%2Fu-boot.git Conditionally perform common relocation fixups Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation.
