[PATCH] flashrom: Add PMC Pm29F002T/B support

[Uwe Hermann]

See patch.

I didn't find timing info in the datasheet after quick glace. Also,
the 8192 is pretty arbitrary as we only do byte-wise programming on
this chip.

page_size usually is the eraseblock size. Please find out the eraseblock
size and fill it in. Thanks.

Thanks, r590.

There's no uniform erase block size I think, there are the following
erase blocks:

Boot Block         16 Kbytes 00000h-03FFFh
Parameter Block 1  8 Kbytes  04000h-05FFFh
Parameter Block 2  8 Kbytes  06000h-07FFFh
Main Block 1      96 Kbytes  08000h-1FFFFh
Main Block 2      128 Kbytes 20000h-3FFFFh

So the 8192 size is probably the best fit until flashrom can handle
non-uniform sectors/blocks, dunno.

Uwe.
