Hi Kyle,

I have added high speed write support to the Dediprog SF100 driver in
flashrom and it should now be close to the native speed seen with the
vendor Windows tool.

However, the Dediprog SF100 needs someone to check what happens on the
SPI bus with the help of a logic analyzer before it is enabled by
default. Right now there is reasonable cause for suspicion that the
Dediprog SF100 uses the FAST_READ command which is not supported by
older flash chips. Similar concerns apply to the write process which may
or may not use the RDSR command after each write.
Reading and writing should be safe for pretty much every SPI flash chip
ever released in the last 3 years, but as long as I'm not 100% sure
about every SPI flash chip supported by flashrom, I fear Dediprog SF100
support will stay disabled by default.

Although I wrote the driver, I do not own a Dediprog SF100, so I have to
wait for someone with enough time and a logic analyzer to check this.

Once we know what the Dediprog SF100 does on the SPI bus, we can enable
it by default in flashrom.

Regards,
Carl-Daniel
