#1735995 — [PATCH v2 0/3] Altera ASMI Parallel II IP Core

From	matthew.gerlach@linux.intel.com
Date	2017-09-20 20:40 +0200
Subject	[PATCH v2 0/3] Altera ASMI Parallel II IP Core
Message-ID	<urRUZ-6Fp-7@gated-at.bofh.it>

From: Matthew Gerlach <matthew.gerlach@linux.intel.com>

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.

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