From d27ef5bf6f5e444141dca6a89c46e667bca64652 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Wed, 20 Oct 2021 20:18:12 +0200 Subject: cpu/x86/mp_init: use cb_err as mp_init_with_smm return type Using cb_err as return type clarifies the meaning of the different return values. This patch also adds the types.h include that provides the definition of the cb_err enum and checks the return value of mp_init_with_smm against the enum values instead of either checking if it's non-zero or less than zero to handle the error case.
