+ * 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.
