Should the ifeq be referring to CONFIG_SYSTEM_REVOCATION_KEYS rather than
CONFIG_SYSTEM_REVOCATION_LIST?  In fact, since S_R_K depends indirectly on
S_B_K, you should be able to just do:

	+obj-$(CONFIG_SYSTEM_REVOCATION_KEYS) += revocation_certificates.o

> +#ifdef CONFIG_SYSTEM_REVOCATION_LIST

Here also?

And here too?

(As an aside, I wonder if SYSTEM_REVOCATION_CERTS would be a better name, but
I'm okay with leaving it as-is for now).
