This is what I get:

$ make ARCH=xtensa O=build/xtensa nommu_kc705_defconfig vmlinux V=1
....
xtensa-linux-gcc-11.1.0 -DKCONFIG_SEED=

/git/arm-soc/arch/xtensa/kernel/head.S: Assembler messages:
/git/arm-soc/arch/xtensa/kernel/head.S:87: Error: invalid register
'atomctl' for 'wsr' instruction

I think there were other errors in the past, but every time I tried
it, the build failed for me.
