2016-04-19	mtd/ifc: Add support for IFC controller version 2.0	Raghav Dogra	1	-18/+18
	The new IFC controller version 2.0 has a different memory map page. Upto IFC 1.4 PAGE size is 4 KB and from IFC2.0 PAGE size is 64KB. This patch segregates the IFC global and runtime registers to appropriate PAGE sizes.

2016-02-01	driver/memory: Removal of deprecated NO_IRQ	Raghav Dogra	1	-1/+1
	Replacing the NO_IRQ macro with 0. If there is no interrupt, returned value will be 0 regardless of what NO_IRQ is defined. Signed-off-by: Raghav Dogra <raghav@freescale.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2014-02-19	driver/memory:Move Freescale IFC driver to a common driver	Prabhakar Kushwaha	1	-0/+309
	Freescale IFC controller has been used for mpc8xxx. It will be used for ARM-based SoC as well. This patch moves the driver to driver/memory and fix the header file includes. Also remove module_platform_driver() and instead call platform_driver_register() from subsys_initcall() to make sure this module has been loaded before MTD partition parsing starts.
