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