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
