Buildroot sets appropriate ENABLE_STACK_PROTECTOR build flag value based on the toolchain global BR2_SSP_* options, and all packages are built with that setting. However it might not be always convenient to automatically infer TF-A stack protection from the toolchain features. For instance, secure memory constraints may become an issue and all the extra TF-A features need to be tuned or disabled in order to shrink TF-A firmware image. Besides, for any value other than "none", TF-A platform specific hook 'plat_get_stack_protector_canary' must be implemented. However this hook is not implemented by all the platforms supported by TF-A. For instance, Allwinner currently does not provide such a hook. Add an new option that a user can toggle to enable or disable SSP in their ATF build. If enabled, the SSP level is automatically inherited from the global setting.

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
