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

| tristate "Texas Instruments EMIF driver" |
| depends on ARCH_OMAP2PLUS |
| select DDR |
| help |
| This driver is for the EMIF module available in Texas Instruments |
| SoCs. EMIF is an SDRAM controller that, based on its revision, |
| supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols. |
| This driver takes care of only LPDDR2 memories presently. The |
| functions of the driver includes re-configuring AC timing |
| parameters and other settings during frequency, voltage and |
| temperature changes |

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

| config OMAP_GPMC_DEBUG |
| bool "Enable GPMC debug output and skip reset of GPMC during init" |
| depends on OMAP_GPMC |
| help |
| Enables verbose debugging mostly to decode the bootloader provided |
| timings. To preserve the bootloader provided timings, the reset |
| of GPMC is skipped during init. Enable this during development to |
| configure devices connected to the GPMC bus. |
| |
| NOTE: In addition to matching the register setup with the bootloader |
| you also need to match the GPMC FCLK frequency used by the |
| bootloader or else the GPMC timings won't be identical with the |
| bootloader timings. |

| config TI_EMIF_SRAM |
| tristate "Texas Instruments EMIF SRAM driver" |
| depends on (SOC_AM33XX || SOC_AM43XX) && SRAM |
| help |
| This driver is for the EMIF module available on Texas Instruments |
| AM33XX and AM43XX SoCs and is required for PM. Certain parts of |
| the EMIF PM code must run from on-chip SRAM late in the suspend |
| sequence so this driver provides several relocatable PM functions |
| for the SoC PM code to use. |
