PS32: 
Not sure if I'm doing something wrong. The patch works so far, but
I don't see any speed increase in my setup. This is with an FT2232H,
bcdDevice 7.00 (not sure if that means something) according to lsusb.
Running it at 15MHz (divisor=4) with a W25Q128FV. Read/erase/write
with random data takes about 11:30min. Maybe it's about 1s faster
with these patches, but that could be just noise. I did most tests
on a 256KiB layout region, and there was no visible difference ~12.3s.
