I don't know how much effort it's worth putting into this, but it /might/ be possible to port U-Boot to the devices, and use that as the "kernel" image that the binary bootloader boots, and then have U-Boot boot a kernel from a filesystem in the "normal" way. That's kind what I did by porting U-Boot to the Raspberry Pi. It would certainly increase the possibility of a distro supporting these devices in a generic way, as well as avoiding the need for hard-coded command-lines, memory layout, etc. in the DT files. We'd have to make sure that any installer didn't change the GPT layout, since then it'd get out of sync with the tegrapt partitions, which could cause the bootloader to fail. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
