Log:
SVN rev 194670 on 2009-06-22 22:54:13Z by sam
o add a bus space tag that forces a 2usec delay between r/w ops; this is
used for the optional GPS+RS485 uarts on the Gateworks Cambria boards
which otherwise are unreliable
o setup the hack bus space tag for the GPS+RS485 uarts
o program the gpio interrupts for the uarts to be edge-rising
o force timing on the expansion bus for the uarts to be "slow"
Thanks to Chris Lang of Gateworks for these tips.
