[LinuxBIOS] Flashrom

[Markus Boas]

Today I retry to  add support for the Winbond W29C040P chip.
But read theams work not correct.
I look into the files with "hexer" it look so much different from a Epia Cl 
save.

The Target is a Compaq T30, it is a thin client with a Geode GX1.

I append the bios save. Can anybody say if this is ja possibel file?

Please post a patch and perhaps a link to the data sheet. Then we can
look at it as well.

I found my fault, I don't realised the 256 Bit instatt of 128 Bit Pagesize.
So it read, write and verifiy.

Thanks, committed in r2752.

The patch was somehow malformed (didn't apply), but I fixed that
manually.

Cheers, Uwe.
