I don't think it works without INTEL_STRATIX10_SERVICE, maybe:

	depends on ARCH_INTEL_SOCFPGA || COMPILE_TEST
	depends on INTEL_STRATIX10_SERVICE

But INTEL_STRATIX10_SERVICE depends on HAVE_ARM_SMCCC, and they all
require arch configurations...

Yeah I don't think INTEL_STRATIX10_SERVICE is needed for COMPILE_TEST.

Have you actually passed compilation without INTEL_STRATIX10_SERVICE?
I can't image how it works without stratix10_svc_xx kAPI definitions.

Based on kernel test bot, It seems INTEL_STRATIX10_SERVICE needs
COMPILE_TEST too.

It also needs fixing. On 32-bit, I get this output:
