602 * Timers Prescale (PTP) value in the Memory Refresh Timer Prescaler Register
603 * (MPTPR) (10-32) must also be set up (it used to be called the Periodic Timer
604 * Prescaler, hence the P instead of the R). The refresh timer period is given
605 * by (note that there was a change in the 8260 UM Errata):
607 * TimerPeriod = (PSRT + 1) / Fmptc
609 * where Fmptc is the BusClock divided by PTP. i.e.
611 * TimerPeriod = (PSRT + 1) / (BusClock / PTP)
615 * TImerPeriod = (PTP * (PSRT + 1)) / BusClock
617 * The requirement for the Toshiba TC59SM716FTL-10 is that there must be
618 * 4K refresh cycles every 64 ms. i.e. one refresh cycle every 64000/4096
621 * So PTP * (PSRT + 1) <= 15.625 * BusClock. At 66.666MHz, PSRT=31 and PTP=32
622 * appear to be reasonable.

638 * "The IO Board is fitted with a Xilinx XCV300E main FPGA. Provision is made
639 * for configuring an optional FPGA on the mezzanine interface.
641 * Access to the FPGAs may be divided into several catagories:
644 * 2. Register mode access
645 * 3. Port mode access
647 * The main FPGA is supported for modes 1, 2 and 3. The mezzanine FPGA can be
648 * configured only (mode 1). Consequently there are four access types.
650 * To improve interface performance and simplify software design, the four
651 * possible access types are separately mapped to different memory banks.
653 * All are accessed using the local bus."
