PIIX flashing woes with SST29EE010

[Jeremy Jackson]

FYI,

A problem I was having that *appeared* to be a problem with
getting writes to the flash chip, wasn't

It turns out that SST's datasheet for SST29EE010 is incorrect.
It turns out that the part I have *doesn't* respond to "new" style
ID mode entry sequence, as indicated in the manual.
It only responds to the "old" AA 55 80 AA 55 60 sequence.

I should have a generic PIIX map driver for MTD soon now.
