Processor System-On-A-Chips. These parts include a number
of integrated peripherals, interfaces and DSPs in addition to
a variety of MIPS cores.

* It is convenient to program the OATRAN register so that

*
* The only hard restrictions on the value of OATRAN is that
* OATRAN must not be programmed to allow translated memory
* addresses to fall within the lowest 512MB of
* PCI address space. This region is hardcoded
* for use as Athena PCI Host Controller target
* access memory space to the Athena's SDRAM.
*
* Note that OATRAN applies only to memory accesses, not
* to I/O accesses.
*
* To program OATRAN to make Athena virtual address space
* and PCI address space have the same values, OATRAN
* is to be programmed to 0xB8000000. The top seven
* bits of the value mimic the seven bits clipped off
* by the PCI Host controller.
*
* With OATRAN at the said value, when the CPU does
* an access to its virtual address at, say 0xB900_5000,
* the address appearing on the PCI bus will be

* SMP/VPE-safe functions to access "registers" (see note).
*
* NOTES:
* - These macros use ll/sc instructions, so it is your responsibility to
* ensure these are available on your platform before including this file.
* - The MIPS32 spec states that ll/sc results are undefined for uncached
* accesses. This means they can't be used on HW registers accessed
* through kseg1. Code which requires these macros for this purpose must
* front-end the registers with cached memory "registers" and have a single
* thread update the actual HW registers.
* - A maximum of 2k of code can be inserted between ll and sc. Every
* memory accesses between the instructions will increase the chance of
* sc failing and having to loop.
* - When using custom_read_reg32/custom_write_reg32 only perform the
* necessary logical operations on the register value in between these
* two calls. All other logic should be performed before the first call.
* - There is a bug on the R10000 chips which has a workaround. If you
* are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
* to be non-zero. If you are using this header from within linux, you may
* include <asm/war.h> before including this file to have this defined
* appropriately for you.
