Subject: [U-Boot] [PATCH 00/17] x86: Rework of board init code (plus support patches)
Date: Mon, 2 Jan 2012 15:09:17 +1100 [thread overview]
Message-ID: <1325477374-6417-1-git-send-email-graeme.russ@gmail.com> (raw)
Happy New Year!
I was thinking I would do another RFC, but instead I pulled an all-nighter
to get this series cleaned up ready for mainline
There a two major architectural changes introduced by this series:
- The global data pointer is converted to a psuedo register implementation
which allows global data to be access pre and post relocations like all
other aches
- The init sequences in board.c are reduced to be purely to loops which
execute arrays of init functions
All patches are checkpatch clean
Series is rebased to commit bfcc40bb09b05c90cc3b1496abb270eb8aa72134
(Merge branch 'next' of ../next)
Regards,
Graeme
