| H A D | malta-init.c | ecafe3e9 Tue Sep 22 13:58:43 CDT 2015 Paul Burton <paul.burton@imgtec.com> MIPS: Malta: Register UP SMP ops if all else fails
If we fail to register any real SMP implementations, fall back to
registering the dummy UP implementation. Otherwise when we build an SMP
kernel & run it on a system where the SMP implementations fail to probe
(eg. QEMU) the kernel will perform a NULL dereference attempting to call
mp_ops->smp_setup() from plat_smp_setup().
Notably this fixes booting kernels with CPS SMP enabled on QEMU, which
doesn't currently implement the CM, CPC or GIC.
