 41	depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
 42	help
 43	  This driver is for the AEMIF module available in Texas Instruments
 44	  SoCs. AEMIF stands for Asynchronous External Memory Interface and
 45	  is intended to provide a glue-less interface to a variety of
 46	  asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
 47	  of 256M bytes of any of these memories can be accessed at a given
 48	  time via four chip selects with 64M byte access per chip select.

 54	help
 55	  This driver is for the EMIF module available in Texas Instruments
 56	  SoCs. EMIF is an SDRAM controller that, based on its revision,
 57	  supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
 58	  This driver takes care of only LPDDR2 memories presently. The
 59	  functions of the driver includes re-configuring AC timing
 60	  parameters and other settings during frequency, voltage and
 61	  temperature changes

 65	select GPIOLIB
 66	help
 67	  This driver is for the General Purpose Memory Controller (GPMC)
 68	  present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
 69	  interfacing to a variety of asynchronous as well as synchronous
 70	  memory drives like NOR, NAND, OneNAND, SRAM.

 74	depends on OMAP_GPMC
 75	help
 76	  Enables verbose debugging mostly to decode the bootloader provided
 77	  timings. To preserve the bootloader provided timings, the reset
 78	  of GPMC is skipped during init. Enable this during development to
 79	  configure devices connected to the GPMC bus.
 80
 81	  NOTE: In addition to matching the register setup with the bootloader
 82	  you also need to match the GPMC FCLK frequency used by the
 83	  bootloader or else the GPMC timings won't be identical with the
 84	  bootloader timings.

110	  Say Y for reporting of errors from the Freescale CoreNet
111	  Coherency Fabric.  Errors reported include accesses to
112	  physical addresses that mapped by no local access window
113	  (LAW) or an invalid LAW, as well as bad cache state that
114	  represents a coherency violation.
