Hi York, There is no generic driver. AFAIK. Having worked on both mpc85xx and ARM
I can tell you about samsung 5250. There are 2 uboots (one spl and other main). In case of sd/mmc boot the internal rom copies the spl uboot to iRAM and the spl boot loader initialises the DDR3. you can check for board/samsung/smdk5250/dmc_init_ddr3.c -Regards mj On 9/17/13, York Sun <york...@freescale.com> wrote: > Albert, > > Pardon me if this is a dumb question.
