Just to clarify, Ron, people are talking about EPIA-M here.
And the code snippet above is from vt8601/raminit.inc.
EPIA-M doesn't use vt8601.
EPIA and EPIA-M are two totally different boards (different chipsets,
etc).

People with EPIA are seemingly OK with my hack to the SDRAM code of 8601.
However, EPIA-M users need to tweak the hardcoded magic numbers
in the DDR code of vt8623.

So, please open a epia-m directory, instead of epia, in the freebios2 tree.
