- * 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 write
- * to '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.
