[flashrom] Truncating flash for oversized image

[Rob Shore]

Hello!

I've just discovered Flashrom as a way to use a Dediprog SPI programmer
with MacOS, which is awesome.  I've got a bit of a strange question though:

I've got a 1Mbit rom on a board, but the image I was given for it is for a
2Mbit part. The firmware itself in the raw image is < 1Mbit, but the file
is still larger than my ROM. Flashrom won't run the flash saying "Error:
Image size (262144 B) doesn't match the flash chip's size (131072 B)!",
which is technically correct. Is there a way to force the flash, and just
have the process end after the first 131072B, which would result in the
data I need being on the ROM?

Thanks, and looking forward to using this tool some more!
