Merge tag 'mips_5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Thomas Bogendoerfer: - added support for MIPSr5 and P5600 cores - converted Loongson PCI driver into a PCI host driver using the generic PCI framework - added emulation of CPUCFG command for Loogonson64 cpus - removed of LASAT, PMC MSP71xx and NEC MARKEINS/EMMA - ioremap cleanup - fix for a race between two threads faulting the same page - various cleanups and fixes * tag 'mips_5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (143 commits) MIPS: ralink: drop ralink_clk_init for mt7621 MIPS: ralink: bootrom: mark a function as __init to save some memory MIPS: Loongson64: Reorder CPUCFG model match arms MIPS: Expose Loongson CPUCFG availability via HWCAP MIPS: Loongson64: Guard against future cores without CPUCFG MIPS: Fix build warning about "PTR_STR" redefinition MIPS: Loongson64: Remove not used pci.c MIPS: Loongson64: Define PCI_IOBASE MIPS: CPU_LOONGSON2EF need software to maintain cache consistency MIPS: DTS: Fix build errors used with various configs MIPS: Loongson64: select NO_EXCEPT_FILL MIPS: Fix IRQ tracing when call handle_fpe() and handle_msa_fpe() MIPS: mm: add page valid judgement in function pte_modify mm/memory.c: Add memory read privilege on page fault handling mm/memory.c: Update local TLB if PTE entry exists MIPS: Do not flush tlb page when updating PTE entry MIPS: ingenic: Default to a generic board MIPS: ingenic: Add support for GCW Zero prototype MIPS: ingenic: DTS: Add memory info of GCW Zero MIPS: Loongson64: Switch to generic PCI driver ...

- * 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.
