Add support for the Cadence QSPI controller. This controller is
present in the Intel Lightning Mountain(LGM) SoCs, Altera and TI SoCs.
This driver has been tested on the Intel LGM SoCs.
This driver does not support generic SPI and also the implementation
only supports spi-mem interface to replace the existing driver in
mtd/spi-nor/cadence-quadspi.c, the existing driver only support SPI-NOR
flash memory
Is it really supporting SPI NORs only, or is it just that you only
tested it with a spi-nor?
The existing drivers/mtd/spi-nor/cadence-quadspi.c supports SPI-NORs
only, because the driver is developed
such a way that it does not support other SPI based flash memories, also
never uses SPI/SPI-MEM based framework.
So we Vignesh suggested me to develop the new driver which supports
both SPI-NOR and SPI-NAND based on the SPI-MEM framework.
Hm, your commit message makes it sound like even the new driver isn't
generic enough to support SPI NANDs. Maybe there's something to improve
to clarify the fact that this new version is not limited to SPI NORs.
Thanks! for the suggestions to remind me to add.
sure, I will add more information about supporting SPI-NOR and SPI-NAND
Regards
Vadivel
