/* 
 * Static I/O regions.
 *
 * Most of the registers are clumped in 4K regions spread throughout
 * the 0xc0000000 -> 0xc0100000 address range, but we just map in
 * the whole range using a single 1 MB section instead of small
 * 4K pages.  This has two advantages for us:
 *
 * 1) We use only one TLB entry for large number of on-chip I/O devices.
 *
 * 2) We can easily set the Section attributes to XCB=101 on the IXP2400
 *    as required per erratum #66.  We accomplish this by using a
 *    new MT_IXP2000_DEVICE memory type with the bits set as required.
 *
 * CAP stands for CSR Access Proxy.
 *
 * If you change the virtual address of this mapping, please propagate
 * the change to arch/arm/kernel/debug.S, which hardcodes the virtual
 * address of the UART located in this region.
