/*
|

* 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.

|
||||
* Notes:
|
||||
* 1) The SPI registers are split into two blocks, one offset from the
|
||||
* MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
|
||||
* 0x68. The SPI driver definitions for the register must be aware
|
||||
* of this.
|
||||
* 2) The block copy engine register are divided into two regions, one
|
||||
* for the control/configuration of the engine proper and one for the
|
||||
* values of the descriptors used in the copy process. These have
|
||||
* different base defines (CTRL_BASE vs DESC_BASE)
|
||||
* 3) These constants are for physical addresses which means that they
|
||||
* work correctly with "ioremap" and friends. This means that device
|
||||
* drivers will need to remap these addresses using ioremap and perhaps
|
||||
* the readw/writew macros. Or they could use the regptr() macro
|
||||
* defined below, but the readw/writew calls are the correct thing.
|
||||
* 4) The UARTs have an additional status register offset from the base
|
||||
* address. This register isn't used in the standard 8250 driver but
|
||||
* may be used in other software. Consult the hardware datasheet for
|
||||
* offset details.
|
||||
* 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
|
||||
* start at an offset of 0x84 from the base address but the block of
|
||||
* registers before this is reserved for the security engine. The
|
||||
* driver will have to be aware of this but it makes the register
|
||||
* definitions line up better with the documentation.
