Especially when we want to make use of systemd-repart functionality later, the GPT format is a necessity. Therefore, migrate all images to the GPT format. For some platforms (Raspberry Pi, AM355x, AT91), we still need a legacy MBR partition table so that the ROM code can find a bootable partition (which contains our barebox image). For those cases, transform the image into a hybrid format containing an MBR at offset 0, which contains the VFAT boot partition for the ROM loader, and a protective GPT partition of partition type 0xEE after it to claim the remaining space on the storage medium for GPT purposes. Then a GPT header is added at the default GPT offset of 0x200, which defines the boot partition as well as the root partition, and which is read by Barebox and Linux to boot the system. For images that contain a raw barebox image at a fixed offset outside of a GPT partition, make sure that the GPT does not conflict with the barebox image, and write only the primary GPT header into the hole specified by the barebox image (offset 440 to 1K), but move the GPT partition array to an offset behind the barebox image. (genimage will then also offset the following partitions accordingly.) Remove any 'disk-signature' options, which are not compatible with GPT; genimage will generate a random Disk UUID instead. Also remove any 'partition-type' options, and set the respective partition type GUIDs specified by the Discoverable Partitions Specification [1], or let genimage default to the 'linux-generic' partition type. For the rpi1 image-hdimg, overwrite the upstream hd.config with a hardcoded genimage config file since it is not possible to build a hybrid MBR/GPT image with the image recipe from upstream PTXdist. For the v7a image-hdimg, enable GPT support in the platformconfig menu, and re-add the respective config lines from the upstream version of the config file in order to make GPT work. The images with fixed partition sizes for qemu need to stay below the size specified in the 'size' option, so decrease the size of the last partition further to make space for the secondary GPT header, which will reside in the last block of the image.
