| * This file provides details of the LPDDR2 SDRAM parts used on OMAP5 |
| * EVM. Since the parts used and geometry are identical for |
| * evm for a given OMAP5 revision, this information is kept |
| * here instead of being in board directory. However the key functions |
| * exported are weakly linked so that they can be over-ridden in the board |
| * directory if there is a OMAP5 board in the future that uses a different |
| * memory device or geometry. |
| * |
| * For any new board with different memory devices over-ride one or more |
| * of the following functions as per the CONFIG flags you intend to enable: |
| * - emif_get_reg_dump() |
| * - emif_get_dmm_regs() |
| * - emif_get_device_details() |
| * - emif_get_device_timings() |
