Hi, I did some speed test on 4MB SPI flash:
read: spipgm 2:41 flashrom 2:44
erase spipgm 0:21 flashrom 3:34
So you can see the read speed has improved :)

Great. Please note that the parameter changed from -p rayer_bitbang_spi to -p rayer_spi because the short form is faster to type, and users do not care at all about bitbanging.
