Hi all,
Here is a kernel driver for the Cadence QSPI Flash Controller driver
which uses the spi-nor framework. I'm putting it out here for
comments.
Here at Altera, we use the Cadence QSPI in our SoCFPGA systems. We've had
a spi driver for this IP for some time now, but it needed some patches
in the spi subsystem. and so was going to be difficult to upstream.
I ported it over to the spi-nor framework which got rid of the ugly
patches, and also got rid of a bunch of spi_transfer code.
It's based on the master branch of l2-mtd.git. Tested on Altera's
Cyclone5 dev kit.
So here it is, let me know what you all think, please.
Thanks,
Graham Moore
