Hi Youling,
When I build Huacai's tree
(https://github.com/loongson/linux/commits/loongarch-next), there is a
strange error linking vmlinux:
ld: arch/loongarch/kernel/machine_kexec.o: in function `machine_kexec_prepare':
/home/xry111/git-repos/linux/arch/loongarch/kernel/machine_kexec.c:70: undefined reference to `fdt_check_header'
Not sure why...
