all the API's in this driver purely on spi-nor specific, so couldn't
proceed to adapt.
Are these completely separate IPs or are they just different versions of
the same IP?
These are same IPs , but different features Enabled/Disabled depends upon
the SoC vendors.
for e.g: Intel LGM SoC uses the same IP, but without DMA and Direct access
controller.
also dedicated support to flash devices.
If it's different versions of the same IP then everything should be in
one driver with the optional features enabled depending on what's in a
given system.
Agreed!, I am trying to adapt the driver/mtd/spi-nor/cadence-quadspi.c
and newly sent patches
in a single driver file, also trying to use spi_mem_ops framework.
With Best Regards
