In latest firwmare the SPIRA is split into two portions, a hypervisor
initialized and managed portion and a service processor (FSP) built portion,
to accommodate secure boot. The hypervisor portion will be referred to as
the SPIRA-H and the FSP portion referred to as the SPIRA-S.
The legacy N-tuples that are no logner being used have been removed. N-tuples
that are initialized by the hypervisor at compile/build time but not modified
by the FSP reside in the SPIRA-H. All other N-tuples reside in the SPIRA-S that
is built dynamically by the FSP at the beginning of that HDAT memory pointed to
by the “Host Data Area” N-tuple in SPIRA-H.
This patchset adds support for new SPIRA format.
I've tested this patch on P8 and P7. Its working fine on both P8 (new SPIRA
format) and P7 (legacy SPIRA format). I will check with FW folks to make
sure we are passing all the information expected by FSP.
