Subject: Blackfin: stick ins/outs funcs into their own .text section
X-Git-Tag: v2010.12-rc2~46^2^2~1
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=cd97dd4f2c80900a295ec1b7fc6c789b94455c4e;p=u-boot

Blackfin: stick ins/outs funcs into their own .text section

This lets the linker garbage collect these functions when they aren't
actually used by placing them into the standard .text.<func> section.
