[coreboot] [commit] r5779 - in trunk/src: cpu/amd/model_lx mainboard/amd/db800 mainboard/amd/norwich mainboard/artecgroup/dbe61 mainboard/digitallogic/msm800sev mainboard/iei/pcisa-lx-800-r10 mainboard/lipper...

New Revision: 5779
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5779

Log:
Set up an arbitrary amount of system memory on Geode LX, so
coreboot_ram can be unpacked to 1MB. The value is quickly
replaced with the real value later, thus causing no harm.

Move RAMBASE to the default of 1MB for the affected boards
