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

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

77 Enables verbose debugging mostly to decode the bootloader provided
Tony Lindgrenbe59b6192015-10-12 16:19:54 -070078 timings. To preserve the bootloader provided timings, the reset
79 of GPMC is skipped during init. Enable this during development to
80 configure devices connected to the GPMC bus.
81
82 NOTE: In addition to matching the register setup with the bootloader
83 you also need to match the GPMC FCLK frequency used by the
84 bootloader or else the GPMC timings won't be identical with the
85 bootloader timings.

91 This driver is for the EMIF module available on Texas Instruments
92 AM33XX and AM43XX SoCs and is required for PM. Certain parts of
93 the EMIF PM code must run from on-chip SRAM late in the suspend
94 sequence so this driver provides several relocatable PM functions
95 for the SoC PM code to use.
