This version bump is needed to pass the ATF test with hardening option enabled (-fstack-protector-strong) With the version v2.2, ATF fail due to undefined references: ./build/juno/release/bl2u/arm_tzc400.o: In function `arm_tzc400_setup': arm_tzc400.c:(.text.arm_tzc400_setup+0x10): undefined reference to `__stack_chk_guard' arm_tzc400.c:(.text.arm_tzc400_setup+0x18): undefined reference to `__stack_chk_guard' arm_tzc400.c:(.text.arm_tzc400_setup+0xb8): undefined reference to `__stack_chk_guard' arm_tzc400.c:(.text.arm_tzc400_setup+0xcc): undefined reference to `__stack_chk_fail' Since commitccac9a5bbb, Buildroot no longer forces ENABLE_STACK_PROTECTOR. However, we rely on the ATF build system to handle it correctly, and this wasn't the case in v2.2.

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.
