Is it really supporting SPI NORs only, or is it just that you only
tested it with a spi-nor?

Reported-by? What has been reported?

Looks like this could be split in several patches to ease the review:

1/ convert to spi-mem
2/ move the driver to drivers/spi
3/ add support for intel,lgm-qspi

other than that, that's good to see one more spi-nor controller driver
converted to spi-mem.
