| |
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.
Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Acked-by: Arnd Bergmann <arnd@arndb.de> --- Changes for v2: - Move fsl_ifc in driver/memory
Changes for v3: - move device tree bindings to memory
Changes for v4: Rebased to git://git.kernel.org/pub/scm/linux/kernel/git/scottwood/linux.git
Changes for v5: - Moved powerpc/Kconfig option to driver/memory
