No. I knew that a patch existed, but I wrote this from scratch. I scanned through the code, and it required a new set of commands, which I didn't like. I wanted it to link in with the existing commands better. I think that code was also targeted at a specific device. Also, I already had some working SPI flash "bit/bang" code which was easy enough to port to UrJtag. So, in the end I didn't use any of the old openwince SPI code.
Also, FYI, I intend to expand this to I2C flash and eeprom devices.
