Subject: Revert "Align global_data to a 16-byte boundary"
X-Git-Tag: v2015.10-rc2~2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2212e69bc09ac42593794b030d64415293e141ec;p=u-boot

Revert "Align global_data to a 16-byte boundary"

This causes widespread breakage due to the operation of the low-level code
in crt0.S and cro0_64.S for ARM at least.

The fix is not complicated but it seems safer to revert this for now.

This reverts commit 2afddae07523f23f77acd066ad1719f53d289f98.
