17 * This file provides details of the LPDDR2 SDRAM parts used on OMAP4430
18 * SDP and Panda. Since the parts used and geometry are identical for
19 * SDP and Panda for a given OMAP4 revision, this information is kept
20 * here instead of being in board directory. However the key functions
21 * exported are weakly linked so that they can be over-ridden in the board
22 * directory if there is a OMAP4 board in the future that uses a different
23 * memory device or geometry.
25 * For any new board with different memory devices over-ride one or more
26 * of the following functions as per the CONFIG flags you intend to enable:
27 * - emif_get_reg_dump()
28 * - emif_get_dmm_regs()
29 * - emif_get_device_details()
30 * - emif_get_device_timings()
