Since all EFI-based systems support GPT, this commit changes pc_x86_64_efi to use a GPT partition table. It shows an example of how to craft a disk image with GPT partitioning instead of MBR. This is achieved by means of a post-image script which uses mkdosfs+mcopy+sfdisk, since genimage is unable to deal with GPT. Long term, it would be ideal if genimage had GPT support, but until then, this script shows how to achieve creating a GPT-based disk image. The script was kept as simple as possible to make it easy to understand and adapt for other purposes. The root filesystem location is passed to the kernel by a partition UUID, so it is possible to boot on QEMU, directly from the disk image, or dump the image to a physical device.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
