Thanks Tor -- Now we're both informed of each other's dev. :) First off : the MVSATAHX controller is indeed quite similar between both SoCs, at least from a u-boot perspective, where disk usage is limited to loading a kernel and initrd. I see your sata_mv driver originates in the Linux kernel driver and makes use of DMA. This might be a real gain when loading big files often ; in my case, I considered that u-boot will only kick in once in a while and load a less-than-2MB kernel and possibly a less-than-3MB initrd, and while relying on the IDE PIO code will certainly make it slower than with sata_mv, the occasional couple of 10th of ms is a fair price for the very small footprint -- ED Mini V2 is short on NOR Flash space. Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
