Commita17402e42dhas conditionally enabled NEON and VFPv3 optimizations. However, the VFPv3 logic is causing issues on some targets such as Cortex-A5 with VFPv4-D16 but not VFPv4. Since the ENABLE_VFPV3=ON option only adds CFLAGS, we can always set it to OFF, and let Buildroot pass appropriate CFLAGS. However, the ENABLE_NEON option also adds the build of NEON-specific code, so we keep this logic.

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.
