thanks rudolf for the patch.
the chipset/soc itself seems to be named R8610 afaics. i could not find
any references to R6030 as a model name. the pci id is 6030h though...
i would suggest changing the R6030 strings to R8610 if i am not

please also add a suffix to the function name to indicate the model.

i have verified that this enables write cycles as you said. i am (still)
not familiar with LPC, but there must be a few other things that
are needed to get this chipset to work (at least in non-bifferboard
configurations)(?) and afaics we would also like to check a few other

there is "FRS" which indicates the flash type boot strap, which could
also be X bus. guess X bus does not work transparently, does it?

what about the FRR (flash rom region) registers?

this does not registers a flashrom programmer!?

maybe i am just confused... :)

Kind regards/Mit freundlichen Grüßen, Stefan Tauner
