[PATCH 1/12] mips: PMC MSP71xx core platform
Patch to add core platform support for the PMC-Sierra MSP71xx devices.
Thanks,
Marc
Signed-off-by: Marc St-Jean <Marc_St-Jean@xxxxxxxxxxxxxx>
---
Changes since last post:
- Added msp_twi.c to register resources for TWI, now a platfrom driver.
- Moved msp_eth.c to here from ethernet driver patch. Now platform code
registers resources for platform drivers whether static or modules.
- Minor fix to msp_usb.c to build when USB driver is not enabled.
- Exported prom_getenv() from msp_prom.c so ethernet driver loads as a module.
- Added MSP_TWI_SIZE to msp_regs.h for TWI resource registering.

+ * 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.

+ * SMTC/VPE-safe functions to access "registers" (IMPORTANT: see NOTES).
+ *
+ * Copyright 2005-2007 PMC-Sierra, Inc.
+ *
+ * NOTES:
+ * - Some of the macros defined in this file use LL/SC instructions which
+ * are architecture specific. There use on MSP71XX is dependant on the
+ * behavior of the MIPS 34k core in these devices. They will not work on
+ * other multi-processor architectures or possibly on future VPE-based
+ * cores.
+ * - 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. Only perform the necessary logical
