restructuring of the driver. I've tried to preserve the other silicon
workarounds that we've added over the years, but haven't had a chance
to extensively test on other hardware. On my AT91RM9200 with 30MHz/1
wire/64 block transfers, I've been able to go from ~.66MB/s to
2.25MB/s in the simple tests I performed, almost a 3.5x improvement.
This cuts the boot time almost in half when everything else goes
right (timed from rtc message to login: prompt).
