From what I saw it would require some additional patches to enable SPL_MMC for imx53 and a few more changes to our sdcard layout (FAT vs. EXT4). Seeing all these additional #ifdefs to consider I just don't have a good feeling to port that adhoc for our board. Directly booting Linux still sounds tempting, but for the moment I cannot spend more effort into SPL for mx53cx9020. I will put that on my todo list. But for now I would like to concentrate to get mainline boot on mx53cx9020, again.
I would suggest: 1. I keep m53evk.c untouched for now. 2a. Either patch both mx53cx9020 and mx53loco to avoid static mx53_dram_size, and have the shared code in arch/arm/mach-imx/mx53_dram.c 2b. Or patch only board/beckhoff/mx53cx9020/mx53cx9020.c Fabio, what do you prefer? Regards, Patrick --- Beckhoff Automation GmbH & Co. KG | Managing Director: Dipl. Phys.
