Do we need them all for basic use case? I assume that after build u-boot-mmc.bin size is less than 328 KiB and it will be possible to fit it into HardKernel's SD card layout. Please consult the following link for reference: http://odroid.com/dokuwiki/doku.php?id=en:odroid-xu3 Speaking about the SD card layout. I think that it would be welcome to see ./doc entry for XU3 similar to ./doc/README.odroid -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
