Commitccac9a5bbb("boot/arm-trusted-firmware: don't force ENABLE_STACK_PROTECTOR") fixed a build failure but also effectively disabled SSP entirely for ATF. This is because ENABLE_STACK_PROTECTOR is set to 0 unconditionally in make_helpers/defaults.mk, overwriting any environment set value. So we must pass ENABLE_STACK_PROTECTOR in MAKE_OPTS for it to be effective. But to avoid said build failure we can't pass ENABLE_STACK_PROTECTOR=0. Only pass ENABLE_STACK_PROTECTOR when BR2_TARGET_ARM_TRUSTED_FIRMWARE_SSP is enabled. Drop SSP_LEVEL value for the !BR2_TARGET_ARM_TRUSTED_FIRMWARE_SSP case which is now unused.

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.
