[commit] r939 - in trunk/openbios-devel: include/kernel kernel

[repository service]

Author: afaerber
Date: Sun Oct 31 17:37:33 2010
New Revision: 939
URL: http://tracker.coreboot.org/trac/openbios/changeset/939

Log:
Partially revert r917: Leave bootstrap functionality in kernel/cross.h

The base_address for native bitwidth smaller than host bitwidth
is available only in kernel/bootstrap.c and thus cannot be used
elsewhere.

The bitwidth equality code path will have to be enhanced
for different cell sizes instead.
