Author: quozl

New Revision: 3051
URL: http://tracker.coreboot.org/trac/openfirmware/changeset/3051

Log:
OLPC XO-1.75 - move the ramdisk below load-base, as linux will not boot with it in the second half of 1GB units, add room below load-base, which can be thought of as a border between where stuff is initially loaded into, vs where stuff is moved to, #12008
