+ * Program a UPM with the code supplied in the table.
+ *
+ * The 'dummy' variable is used to increment the MAD. 'dummy' is
+ * supposed to be a pointer to the memory of the device being
+ * programmed by the UPM. The data in the MDR is written into
+ * memory and the MAD is incremented every time there's a read
+ * from 'dummy'. Unfortunately, the current prototype for this
+ * function doesn't allow for passing the address of this
+ * device, and changing the prototype will break a number lots
+ * of other code, so we need to use a round-about way of finding
+ * the value for 'dummy'.
+ *
+ * The value can be extracted from the base address bits of the
+ * Base Register (BR) associated with the specific UPM. To find
+ * that BR, we need to scan all 8 BRs until we find the one that
+ * has its MSEL bits matching the UPM we want. Once we know the
+ * right BR, we can extract the base address bits from it.
+ *
+ * The MxMR and the BR and OR of the chosen bank should all be
+ * configured before calling this function.
+ *
+ * Parameters:
+ * upm: 0=UPMA, 1=UPMB, 2=UPMC
+ * table: Pointer to an array of values to program
+ * size: Number of elements in the array. Must be 64 or less.
