43 | help | |
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. | |

55 | help | |
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 | |

76 | help | |
77 | Enables verbose debugging mostly to decode the bootloader provided | |
be59b619 TL |
78 | 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. | |
