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