- * On SH, we traditionally have the whole physical address space mapped
- * at all times (as MIPS does), so "ioremap()" and "iounmap()" do not
- * need to do anything but place the address in the proper segment. This
- * is true for P1 and P2 addresses, as well as some P3 ones. However,
- * most of the P3 addresses and newer cores using extended addressing
- * need to map through page tables, so the ioremap() implementation
- * becomes a bit more complicated. See arch/sh/mm/ioremap.c for
- * additional notes on this.
