The following commit has been merged in the andy-tracking branch:
commit 84ca90e51953ac15f10b430dfe422896d69c4867
Author: Andy Green <andy at openmoko.com>
Date: Mon Mar 9 21:02:16 2009 +0000
fix-s3c-cpu-detect-make-compatible-atag16.patch
The current version of CPU detection patch from Mark Brown and
Kyungmin Park takes a dump on system_rev. This patch changes it
to retain the low 16 of system_rev from the bootloader ATAG, and
adds access #defines and changes to use them.
No doubt they'll issue a better version of the CPU detection
patch and then this can be reverted.
