+ * of other code, so we need to use a round-about way of finding

+ * 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.
