−| CDMA wants these addresses. Each page in this region corresponds to the same page in the 0x10100000-0x10200000 region. It is unknown if this is just a separate bus and/or if there are any differences in the registers.
+| Pages present in this region correspond to the same respective devices in the 0x10100000-0x10140000 region but don't hold the same registers. They hold the FIFOs instead: the HASH FIFO register is located at 0x10301000. The LgyFb scaler data FIFO are located at 0x10310000 (top) and 0x10311000 (bot), etc. Needed for DMA.
