New subject: New Intel Chipsets

I have added support for some new intel chipsets.
If only we could have saved you from doing this twice:
http://www.flashrom.org/pipermail/flashrom/2010-April/thread.html#2896
http://patchwork.coreboot.org/patch/1208/
...
(At least) for the QM57 which i have tested an additional patch was
needed as some reserved bits in the "Software Sequencing Flash Control
Register" (SSFC) needs to be programmed to 1 in the QM57.

Thanks for finding/adding "B55": the friendly name for this chipset is empty
in forementioned patch (see patchwork).
Do you perchance have a verbose log of flashrom (flashrom -V) from that
chipset ?
