Ok.  We'll put it in.  And it most DEFINITELY needs to go into the
test code for OGD1 (although we'll just hook it to general I/O pins or
headers already on the board).

Just to be clear, however, I'm not going to go up a die size for this
feature.  This will be on a list of optional features.  If we find
outselves in a situation where we're using 104% of the die, then this
feature, along with a number of others, will be voted on, one at a
time, for removal until the design fits and performs correctly.

Do you mean SPI or JTAG or I2C?
