Subject: geode: support Classic MediaGXm
From: takada <takada@xxxxxxxxxxxxx>
I hope to support "classic" MediaGXm in kernel.
The DIR1 register of MediaGXm( or Geode) shows the following values for
identify CPU. For example, My MediaGXm shows 0x42.
We can read National Semiconductor's datasheet without any NDAs.
http://www.national.com/pf/GX/GXLV.html
from datasheets:
DIR1
0x30 - 0x33 GXm rev. 1.0 - 2.3
0x34 - 0x4f GXm rev. 2.4 - 3.x
0x5x GXm rev. 5.0 - 5.4
0x6x GXLV
0x7x (unknow)
0x8x Gx1
In nsc driver of X, accept 0x30 through 0x82. What will 0x7x mean?
