a04f2d9d3a
Patch from Lennert Buytenhek The original version of the chip docs had the PW and SU fields in the slowport write timing control register accidentally reversed. This is mentioned in the errata (documentation change #4) and fixed in newer docs. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* 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.
