Pull mtd updates from Miquel Raynal:
 "NAND changes:

   - Extend SPI NAND continuous read to Winbond devices, which requires
     numerous changes in the spi-{mem,nand} layers such as the need for
     a secondary read operation template

   - Continuous reads in general have also been enhanced/fixed for
     avoiding potential issues at probe time and at block boundaries

  SPI NOR changes:

   - Big set of cleanups and improvements to the locking support.

     This series contains some cleanups and bug fixes for code and
     documentation around write protection. Then support is added for
     complement locking, which allows finer grained configuration of
     what is considered locked and unlocked. Then complement locking is
     enabled on a bunch of Winbond W25 flashes

   - Fix die erase support on Spansion flashes.

     Die erase is only supported on multi-die flashes, but the die erase
     opcode was set for all. When the opcode is set, it overrides the
     default chip erase opcode which should be used for single-die
     flashes. Only set the opcode on multi-die flashes. Also, the opcode
     was not set on multi-die s28hx-t flashes. Set it so they can use
     die-erase correctly

  General changes:

   - A few drivers and mappings have been removed following SoCs support
     removal

   - And again, there is the usual load of misc improvements and fixes"

SPI NOR changes for 7.2

Notable changes:

- Big set of cleanups and improvements to the locking support. This
  series contains some cleanups and bug fixes for code and documentation
  around write protection. Then support is added for complement locking,
  which allows finer grained configuration of what is considered locked
  and unlocked. Then complement locking is enabled on a bunch of Winbond
  W25 flashes.

- Fix die erase support on Spansion flashes. Die erase is only supported
  on multi-die flashes, but the die erase opcode was set for all. When
  the opcode is set, it overrides the default chip erase opcode which
  should be used for single-die flashes. Only set the opcode on
  multi-die flashes. Also, the opcode was not set on multi-die s28hx-t
  flashes. Set it so they can use die-erase correctly.

Merge tag 'mtd/spi-mem-cont-read-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into spi-7.2

Miquel Raynal <miquel.raynal@bootlin.com> says:

Aside from preparation changes in the SPI NAND core, the changes carried
here focus on the shared spi-mem layer which is enhanced in order to
bring two new features:

- The possibility to fill a primary and a secondary operation template
  in the direct mapping structure in order to support continuous reads
  in SPI NAND, which may require two different read operations.

- SPI controllers may indicate possible CS instabilities over long
  transfers by setting a boolean. This capability is related to the
  previous one, the need for it has arised while testing SPI NAND
  continuous reads with the Cadence QSPI controller which cannot, under
  certain conditions, keep the CS asserted for the length of
  an eraseblock-large transfer.

Use additional labels so that a bit of exception handling can be better
reused at the end of two function implementations.

This issue was detected by using the Coccinelle software.

Use local variables for the list entry, mtd_info, and private data while
initializing a new device. This keeps the initialization path easier to
read and publishes the new list entry only after mtd_device_register()
has succeeded.

register_device() links a new slram_mtdlist entry before allocating all
of the state needed by the entry. If a later allocation, memremap(), or
mtd_device_register() fails, the partially initialized entry remains on
the global list. A later cleanup can then dereference or free invalid
state from that failed entry.

Unwind the partially initialized entry and clear the list tail on each
failure path after the entry has been linked.

Replace ppc4xx-specific in_be32/out_be32 with generic ioread32be/
iowrite32be to make the driver portable. Add COMPILE_TEST dependency
to get build coverage on non-ppc4xx architectures.

While at it, replace 4xx with 44x. The latter was removed a while ago
and is only kept for compatibility.

S28Hx-T family has multi-die devices that support die erase opcode.
Update die erase opcode when the device is multi-die.
