Subject: x86: Rearrange the output input to remove BSS
X-Git-Tag: v2013.04-rc2~92
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f82d15ead1badc329c4c804f0405e32289f46dd8;p=u-boot

x86: Rearrange the output input to remove BSS

At present BSS data is including in the image, which wastes binary space.
Remove it by rearranging the sections so that BSS is last.
