 So we have a plan - what else is needed?

+First, some script which can create a large image containing everything we need to flash a bootloader and install a new partition table. I wrote a small script just to do this which can be found [[http://gitorious.org/~marvin24/uboot-ac100/create_bootimage|here]]. It create a large image containing uboot, kernel, initrd, device tree, and u-boot script which is executed on load. This large image is loaded by tegrarcm without use of nvflash or something like that.
+Next step is write some script which runs from the initrd. It needs to:
+  - find the partitions and create a new efi partition table
+  - detect the place where to put the bootloader and flash it
+  - flash the new partiton table
+  - flash (or copy to /boot) the new kernel
+Additionally, the ramdisk could contain a minimal system with network (wifi/usb ethernet/usb gadget) support to present a bootloader menu (e.g. [[http://www.kernel.org/pub/linux/kernel/people/geoff/petitboot/petitboot.html|petitboot]]), to either boot some kernels from some attached storage or via tftp, scp, or similar.
