This patch set adds a spi-nor flash driver for the Altera ASMI Parallel II 
IP Core.  This driver was created based on feedback from Marek Vasut,
Cyrill Pitchen, and Michal Suchanek regarding Version 2 of the Altera
Quadspi Controller: https://lkml.org/lkml/2017/6/26/518

The overall problem with Version 2 of the Altera Quadspi Controller and 
its driver was the fact that there was much duplication of code and logic
with the spi-nor framework.  This new combination of fpga hardware and 
software "gets out of the way" of the spi-nor framework.  The result is a
much simpler driver with the spi-nor framework performing the bulk of the work.

Patch 1 contains the device tree bindings for the driver for
the Altera ASMI-Parallel II IP Core.

Patch 2 contains the driver code for the Altera ASMI-Parallel II IP Core.
This driver supports being configured via a device tree or with platform
data.  In the later case, the memory for the registers has been remapped.
This later case is intended for cases where the Altera ASMI-Parallel II
driver is child of a pcie driver that has already mapped the BAR memory
(See Patch 3).

Patch 3 is for informational purposes only.  The patch is against the
intel-fpga PCIe driver currently being reviewed linux-fpga mailing list.
It shows how a PCIe driver might create an instance of the Altera
ASMI Parallel II spi-nor driver.
