powerpc/85xx: Add support for Integrated Flash Controller (IFC) The Integrated Flash Controller (IFC) is used to access the external NAND Flash, NOR Flash, EPROM, SRAM and Generic ASIC memories.Four chip selects are provided in IFC so that maximum of four Flash devices can be hooked, but only one can be accessed at a given time. Features supported by IFC are, - Functional muxing of pins between NAND, NOR and GPCM - Support memory banks of size 64KByte to 4 GBytes - Write protection capability (only for NAND and NOR) - Provision of Software Reset - Flexible Timing programmability for every chip select - NAND Machine - x8/ x16 NAND Flash Interface - SLC and MLC NAND Flash devices support with configurable page sizes of upto 4KB - Internal SRAM of 9KB which is directly mapped and availble at boot time for NAND Boot - Configurable block size - Boot chip select (CS0) available at system reset - NOR Machine - Data bus width of 8/16/32 - Compatible with asynchronous NOR Flash - Directly memory mapped - Supports address data multiplexed (ADM) NOR device - Boot chip select (CS0) available at system reset - GPCM Machine (NORMAL GPCM Mode) - Support for x8/16/32 bit device - Compatible with general purpose addressable device e.g. SRAM, ROM - External clock is supported with programmable division ratio - GPCM Machine (Generic ASIC Mode) - Support for x8/16/32 bit device - Address and Data are shared on I/O bus - Following Address and Data sequences can be supported on I/O bus - 32 bit I/O: AD - 16 bit I/O: AADD - 8 bit I/O : AAAADDDD - Configurable Even/Odd Parity on Address/Data bus supported Signed-off-by: Dipen Dudhat <Dipen.Dudhat@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
