N/A Summary: Arm64 support for NuttX, Features supported: 1. Cortex-a53 single core and SMP support: it's can run into nsh shell at qemu virt machine. 2. qemu-a53 board configuration support: it's only for evaluate propose 3. FPU support for armv8-a: FPU context switching at NEON/floating-point TRAP is supported. 4. psci interface, armv8 cache operation(data cache) and smccc support. 5. fix mass code style issue, thank for @xiaoxiang781216, @hartmannathan @pkarashchenko Please refer to boards/arm64/qemu/qemu-a53/README.txt for detail Note: 1. GCC MACOS issue The GCC 11.2 toolchain for MACOS may get crash while compiling float operation function, the following link describe the issue and give analyse at the issue: https://bugs.linaro.org/show_bug.cgi?id=5825 it's seem GCC give a wrong instruction at certain machine which without architecture features the new toolchain is not available still, so just disable the MACOS cibuild check at present Signed-off-by: qinwei1 <qinwei1@xiaomi.com>
