[PATCH]Enable flashrom on Wyse Winterm S50.

[Nils]

Hi,
First off all I want to thank all flashrom and coreboot members for their great 
work!
With the help of the little attached patch I was able to Probe, Read, Write 
and Verify a ST49LF020A flashchip on my Wyse Winterm S50 Thin Client with Geode 
GX500 (GX2) processor and CS5536 companion chip.

I hope its the right patch.

Thanks,
Nils.

Hi Nils,

thanks for your patch.
I'm sure it works, but there is a small catch: AFAIK the GX2 can use
multiple companion chips (CS5530 and CS5536). That means your patch
could lead to false positives on some boards.
Does the CS5536 appear in lspci on your board? If yes, can you use the
CS5536 host bridge PCI ID instead?

Regards,
Carl-Daniel
