* These pins are overlaid on mprj_io space. They have the function
* below when the management processor is in reset, or in the default
* configuration. They are assigned to uses in the user space by the
* configuration program running off of the SPI flash. Note that even
* when the user has taken control of these pins, they can be restored
* to the original use by setting the resetb pin low. The SPI pins and
* UART pins can be connected directly to an FTDI chip as long as the
* FTDI chip sets these lines to high impedence (input function) at
* all times except when holding the chip in reset.
*
* JTAG = mprj_io[0] (inout)

* technically use any available I/O pins for the purpose, these
* four pins connect to a pass-through mode from the SPI slave (pins

* can be accessed through the SPI slave even when the processor is in
