37 * Static I/O regions.
38 *
39 * Most of the registers are clumped in 4K regions spread throughout
40 * the 0xc0000000 -> 0xc0100000 address range, but we just map in
41 * the whole range using a single 1 MB section instead of small
42 * 4K pages. This has two advantages for us:
43 *
44 * 1) We use only one TLB entry for large number of on-chip I/O devices.
45 *
46 * 2) We can easily set the Section attributes to XCB=101 on the IXP2400
47 * as required per erratum #66. We accomplish this by using a
48 * new MT_IXP2000_DEVICE memory type with the bits set as required.
49 *
50 * CAP stands for CSR Access Proxy.
51 *
52 * If you change the virtual address of this mapping, please propagate
53 * the change to arch/arm/kernel/debug.S, which hardcodes the virtual
54 * address of the UART located in this region.
