The SPI controller operates on packets which can be variable
length up to 32-bit packets. It also has the ability to be
put in packed or unpacked mode w.r.t each packet. i.e. does
a single fifo register hold >= 1 packet. The current programming
uses 8-bit packets in unpacked mode which means 4 fifo slots
are used for a 32-bit DMA transfter. As the AHB can only operate
on a minimum of 32-bit bursts the triggers need to be programmed
correctly so that there is room for a full 32-bit DMA transaction.
Previously faster SPI clocks just made things magically work.
