When build U-boot with clang with using commands: $ make HOSTCC=clang xenguest_arm64_defconfig $ make HOSTCC=clang CROSS_COMPILE=aarch64-linux-gnu- \ CC="clang -target aarch64-linux-gnueabi" -j8 The compiler reports error: /tmp/start-acdf31.s:330:1: error: symbol '_start' is already defined _start: ^ Because the symbol '_start' has been defined twice, one is defined in arch/arm/cpu/armv8/start.S, another is defined in the header boot0-linux-kernel-header.h. To fix building failure, this patch removes the symbol '_start' from boot0-linux-kernel-header.h.
