v2: - addressed all the comments - all flash parameters and settings are now set in 'struct spi_nor_flash_parameter', for a clearer separation between the SPI NOR layer and the flash params.
Add post_sfdp() hook to tweak flash config. This series opens doors for 5/ from below.
In the quest of moving the manufacturer code out of the spi-nor core, we want to impose the following sequence of calls:
1/ spi-nor core legacy flash parameters init: spi_nor_default_init_params()
2/ MFR-based manufacturer flash parameters init: nor->manufacturer->fixups->default_init()
3/ specific flash_info tweeks done when decisions can not be done just on MFR: nor->info->fixups->default_init()
4/ SFDP tables flash parameters init - SFDP knows better: spi_nor_sfdp_init_params()
5/ post SFDP tables flash parameters updates - in case manufacturers get the serial flash tables wrong or incomplete. nor->info->fixups->post_sfdp() The later can be extended to nor->manufacturer->fixups->post_sfdp() if needed.
Tested on sst26vf064b with atmel-quadspi SPIMEM driver.
