The datasheet states "10 MHz Max Clock Frequency". AFAIK you are using
an Arduino which has a 16 MHz clock, but the maximum SPI frequency the
CPU supports is CLK_cpu/2, i.e. 8 MHz, shouldn't be a problem.
Anyway, serprog supports an spispeed parameter but the programmer has
to support that too (no idea if GNUtoo's code does that).
flashrom -p serprog:dev=/dev/device:baud,spispeed=2M

Possible in theory, but why would it reply with 0x7fff to RDID
commands? I am pretty certain it is an electrical issue on the SPI bus.
