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. Patch 3 contains a work around for some non-standard behavior of EPCQ flash.
