| * 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. |
