- * This file provides details of the LPDDR2 SDRAM parts used on OMAP4430
- * SDP and Panda. Since the parts used and geometry are identical for
- * SDP and Panda for a given OMAP4 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 OMAP4 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()
