SPI-NOR core changes:
- add support for the mt25ql02g and w25q16jv flashes
- print error in case of jedec read id fails
- is25lp256: add post BFPT fix to correct the addr_width
SPI NOR controller drivers changes:
- intel-spi: Add support for Intel Elkhart Lake SPI serial flash
- smt32: remove the driver as the driver was replaced by spi-stm32-qspi.c
- cadence-quadspi: add reset control
mtd: spi-nor: cadence-quadspi: add reset control
Get the reset control properties for the QSPI controller and bring them
out of reset. Most will have just one reset bit, but there is an additional
OCP reset bit that is used ECC. The OCP reset bit will also need to get
de-asserted as well. [1]
The reason this patch is needed is in the case where a bootloader leaves
the QSPI controller in a reset state, or a state where init cannot occur
successfully, the patch will put the QSPI controller into a clean state.
