Subject: [PATCH 00/13] spi: airoha: driver fixes & improvements

This patch series greatly improve airoha snfi driver and fix a
number of serious bug.

Fixed bugs:
 * fix reading/writing of flashes with more than one plane per lun
 * fix inability to read/write oob area
 * fill the buffer with 0xff before writing
 * fix error paths

Improvements:
 * add support of dual/quad wires spi modes in exec_op()
 * support of dualio/quadio flash reading commands
 * remove dirty hack that reads flash page settings from SNFI registers
   during driver startup

Unfortunately I am unable to test the driver with linux at the moment,
so only the following testing was done:
 * Driver compiles without error.
 * All changes were tested with corresponding u-boot driver. U-Boot
   SpiNAND driver was modified as well to matck linux-6.17-rc1.

Mikhail Kshevetskiy (13):
  spi: airoha: remove unnecessary restriction length
  spi: airoha: add support of dual/quad wires spi modes
  spi: airoha: remove unnecessary switch to non-dma mode
  spi: airoha: unify dirmap read/write code
  spi: airoha: switch back to non-dma mode in the case of error
  spi: airoha: fix reading/writing of flashes with more than one plane
    per lun
  spi: airoha: support of dualio/quadio flash reading commands
  spi: airoha: allow reading/writing of oob area
  spi: airoha: buffer must be 0xff-ed before writing
  spi: airoha: avoid setting of page/oob sizes in REG_SPI_NFI_PAGEFMT
  spi: airoha: reduce the number of modification of REG_SPI_NFI_CNFG and
    REG_SPI_NFI_SECCUS_SIZE registers
  spi: airoha: set custom sector size equal to flash page size
  spi: airoha: avoid reading flash page settings from SNFI registers
    during driver startup
