Toshiba NAND flash on CS5530A Southbridge

Toshiba NAND flash on CS5530A Southbridge

[Philip Loewen]

I would like to get linux access to the Toshiba NAND flash 
in my Compaq Evo T20 thin client, made in 2001. I have tried 
many many combinations of the kernel parameters without 
success. RTFM and SFTW have left me no wiser, so I am asking 
here: can anyone suggest a working recipe?

The thin client has a Geode GX1 CPU, an AMD CS5530A 
Southbridge, and 48MB of flash memory soldered to the 
mainboard: Toshiba TC58128FT or some near relation. The 
kernel version is 2.6.24-gentoo-r8. At some early stage I 
stumbled upon some combination of keys that caused 
interesting-sounding devices like /dev/mtd0 to appear, but 
they didn't seem mountable so I adjusted the kernel and 
recompiled without noting the settings I had -- ouch! -- and 
now even that small glimmer of hope has gone.

Any helpful suggestions would be most welcome. Thanks.
