Subject: mpc83xx: Size optimization of start.S
X-Git-Tag: v2009.03-rc1~173^2^2~7
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=455a46915b82896cc2070eb326d075555c2bc580;p=u-boot

mpc83xx: Size optimization of start.S

Currently there are in excess of 100 bytes located at the beginning of the image
built by start.S that are not being utilized.  This patch moves a few functions
into this part of the image.  This will create a greater number of *available*
bytes that can be used by board specific code in NAND builds and will decrease
the size of the assembled code in other builds.
