hello daniel,

if you could provide some verbose (-V) logs of said behavior we might
be able to tell you the reason. i believe that sometimes parts of the
chip's contents and the file to be written are equal. flashrom will not
try to erase those sectors then and just print S (for skip; in verbose
mode only).
if you have not found a bug, then there is probably not much potential
for speedup on internal programmers (i.e. motherboards). they are
usually limited by the speed of the flash chip and/or its bus. erasing
flash chips can take quite some time - more than one minute - depending
on the model. in your case though it seems to be very fast according
to the data sheet... what durations are we talking about btw?

i have also marked the SST49LF008A as fully tested and will commit that
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
