[LinuxBIOS] PATCH: flashrom support for SST 49LF020A.

[Uwe Hermann]

Hi,

here's a small patch to add support for the SST 49LF020A to flashrom.

I only tested probing and reading the chip, I don't want to test
writing, as the chip on my test-board is soldered on.
I'm guessing that it should work, though, as it shares most code with
some very similar chips.


Uwe.
