I copied this from Table 17 in the Beagle HRM. The different options
are set via a mux control register in the OMAP3. I think Option A is
the best place to start. My hope is the MMC interface can move a lot
of data.
Agree. Checking the specs on the MMC interface shows that it should be
able to clock arount 50MHz. I don't know how much of that is overhead,
nor what sort of twiddling you need to do to the drive logic to handle a
non-MMC/SD device on the other side (anyone have the TRM for the
OMAP3?), but it should be possible to get a lot of data through it.
Anyone know if the pin options are individually selectable? If so then
it would be good to use some GPIO or SPI for FPGA configuration
You should be able to drive the mmc pins in SPI mode, since that's what
SDIO basically is :)

Plus - good to have that I2C interface on there - a lot of RF front-end
devices use I2C for configuration.
