Hi,

The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI flash directly in memory. However, for writing in the flash the communication has to be done by software.
Each of the signal used for the SPI are exposed in a single register. In order to be able to use the soft-spi driver, the management of this pin is done through this simple gpio driver.
Even if the main purpose of this driver is to be used by soft-spi, it can still be used as a normal gpio driver but with limitation: for example the first pin can't be used as output.

Changelog: v1 -> v2:
- use const and static when needed
- fix style
- use dev_remap_addr
I sent this version 2 months ago and addressed all the comments, how could we going further ?
Thanks,
Gregory
I'll apply it along with your Ocelot/Luton series. It only makes sense to merge a new driver if there is a user for it ;)
