 * This file provides details of the LPDDR2 SDRAM parts used on OMAP5

 * 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()
