Subject: [PATCH 0/5] mtd: spi-nor: move manuf out of the core - batch 0

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

This series is a prerequisite for the effort of moving the
manufacturer specific code out of the SPI NOR core.

The scope is to move all [FLASH-SPECIFIC] parameters and settings
from 'struct spi_nor' to 'struct spi_nor_flash_parameter'. We will
have a clear separation between the SPI NOR layer and the flash
parameters and settings.

'struct spi_nor_flash_parameter' describes the hardware capabilities
and associated settings of the SPI NOR flash memory. It includes
legacy flash parameters and settings that can be overwritten by the
spi_nor_fixups hooks, or dynamically when parsing the JESD216
Serial Flash Discoverable Parameters (SFDP) tables. All SFDP params
and settings will fit inside 'struct spi_nor_flash_parameter'.

Tested uniform and non-uniform erase on sst26vf064b flash using the
atmel-quadspi driver.

In order to test this, you'll have to merge v5.3-rc5 in spi-nor/next.
This patch depends on
'commit 834de5c1aa76 ("mtd: spi-nor: Fix the disabling of write protection at init")

Tudor Ambarus (5):
  mtd: spi-nor: Regroup flash parameter and settings
  mtd: spi-nor: Use nor->params
  mtd: spi-nor: Drop quad_enable() from 'struct spi-nor'
  mtd: spi-nor: Move clear_sr_bp() to 'struct spi_nor_flash_parameter'
  mtd: spi-nor: Move erase_map to 'struct spi_nor_flash_parameter'
