The ARMv8 cores have a mandatory FPU unit called FP-ARMv8, so we: - add a new hidden Config.in option for the availability of this unit (BR2_ARM_CPU_HAS_FP_ARMV8) - allow the selection of a possible choice in the "Floating point strategy", and add two new choices: BR2_ARM_FPU_FP_ARMV8 and BR2_ARM_FPU_NEON_FP_ARMV8. - specify the -mfpu values for BR2_ARM_FPU_FP_ARMV8 and BR2_ARM_FPU_NEON_FP_ARMV8 cases, when used on ARM 32 bits (-mfpu doesn't exist on ARM64, instead -mcpu modifiers are used, so they will be added on a per-core basis).

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