As the previous comment indicated, this null check is
currently superfluous, but adding it in makes Coverity
happy, and future-proofs the code in case someone changes
the internals of 'find_fcba' later and forgets/doesn't know
to update this error check.

This cpu_index() implementation assumes that cpu_index() function
might always getting called from coreboot context (ESP stack
pointer will always refer to coreboot).
This might not be true in case of proposed PI spec MP_SERVICES_PPI
implementation, where FSP context (stack pointer refers to fsp)
will request to get cpu_index(), natural alignment logic will
use ESP and retrieve struct cpu_info *ci from (stack_top - 8 byte).
This is not the place where cpu_index is actually stored by
ramstage c_start.S
Hence this patch tries to remove those dependencies while retrieving
cpu_index(), rather it uses cpuid to fetch lapic id and matches with
cpus_default_apic_id[] variable to return correct cpu_index().

Some edk2 vendorcode headers define an ASSERT macro. They're guarded
with an #ifndef ASSERT, but if coreboot's assert.h gets included after
that header, we still have a problem. Add code to assert.h to undefine
any rogue definitions that may have already been set by vendorcode
headers.
This is ugly and should only be a stopgap... it would be nice if someone
maintaining those vendorcode parts could eventually replace it with a
better solution. One option would be to use a "guard header" for every
vendorcode header we want to pull into normal coreboot code which would
chain-include the vendorcode header and then undefine anything that
clashes with coreboot again.

the stage that's loading the verstage can execute after verification has
run (because the verstage will return to it when it's done). In the
other case, the stage that loads verstage really just loads it and will
never do anything again after hand-off, so it's guaranteed to always
execute before verification.
