add an uboot able to boot a kernel in an ubi partition This uboot also has a "recovery" feature, before booting from flash it will try to boot a initramfs image called "initramfs.bin" from a FAT32-formatted USB drive connected to the USB 2.0 port. (u-boot lacks drivers for usb 3.0 controllers) Just rename the initramfs image and place it on the usb drive, the uboot will load it. In case there is no USB drive or no such file is found, the uboot will boot from internal flash. The whole check takes less than a second, boot times are not impacted.
