gcc-runtime/libatomic explicitly add -march=armv8-a+lse for all arch64 but cortex-a55 is armv8.2-a, which essentially conflicts, so let gcc override it by not forcing the -mcpu option from TUNE_CCARGS (From OE-Core rev: 882df891e13ce5c64718c364efb9ef2bf189eabf) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
