What do you plan to use this for? kdump? I plan to burn a kernel (and a small stub, and a DTB) into flash instead of U-Boot, and hence not have to rely on any bootloader. Even ignoring that, a quick scp of a new kernel to a target followed by a kexec is faster than rebooting all the way through U-Boot's slower Ethernet support to boot a new kernel. -- 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
