This patch adds support for the SST25WF080 1 Mbyte SPI flash chip. It
has been very minimally tested (basically one each read/write/verify),
on Windows XP with a USB Blaster as the programmer. It worked,
although it was horribly slow (at least 15 minutes to program 1 MB) -
but I have not otherwise used this hardware/software combination to
program anything, so that might be normal.
