[PATCH v2 0/2] NXP SPIFI driver for LPC18xx/43xx familiy

[Joachim Eastwood]

This patch set adds a SPI-NOR driver for the NXP SPI Flash (SPIFI)
controller that can be found on newer NXP MCUs. For example on the
LPC18xx and LPC43xx familiy.

NXP SPIFI is a specialized SPI interface for serial Flash devices.
It supports one Flash device with 1-, 2- and 4-bits width in SPI
mode 0 or 3. The controller operates in either command or memory
mode. In memory mode the Flash is made accessible for the CPU as
normal memory.

This version address the comments from Ezequiel Garcia.
See: http://marc.info/?l=linux-arm-kernel&m=143300098616001&w=2

Changes since v1:
 - use readb_poll_timeout instead of open coding
 - cache current mode (memory/command)
 - depend on HAS_IOMEM
 - removed stray white space
 - removed leftover debug print

Support for LPC18xx/43xx can found in linux-next now.

Patch against l2-mtd.git master branch.
