We now have 3 different options to select an image as the BL33 stage of TF-A: Barebox, U-Boot or EDK2. Technically speaking, they are mutually exclusive: they all specify a BL33= variable to the TF-A build, and TF-A can only support a single BL33 stage. However, as pointed out by Vincent Fazio in [0] there is nothing that prevents selecting Barebox, U-Boot and EDK2 together, even though it doesn't make sense. To address this, this commit introduces a choice...endchoice block, into which the Barebox, U-Boot and EDK2 options are moved. An additional "none" option is added, which is the default, and corresponds to not having any BL33 image. Since we keep the same name for the options, no legacy handling is necessary.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
