OPAL/MPIPL: Processor Dump Area Table interfaces
This patch adds support to collect processor architected register data.
SBE <--> Hostboot :
-------------------
During first boot, hostboot reserves memory to copy architected register
data by SBE and sends address to each SBE (see commit 9f49d11b). During
MPIPL SBE collects architected register data and copies to reserved
memory.
Hostboot <--> Hypervisor :
--------------------------
HDAT/SPIRAH has new ntuple (Processor Dump Area) to pass various
architected register data. During IPL/runtime hypervisor reserves memory
for architected register data and updates SPIRAH.
During MPIPL (istep 14.8), hostboot converts SBE formated architected
registers data to HDAT format and copies to hypervisor reserved memory.
It uses NACA/SPIRAH pointers to get hypervisor reserved memory details.
Hostboot has to update SPIRAH ntuple after loading new LID to memory.
Hence this patch introdues below new attributes:
- PDA_CAPTURED_THREAD_REG_ARRAY_ADDR
- PDA_CAPTURED_THREAD_REG_ARRAY_SIZE
- PDA_THREAD_REG_ENTRY_SIZE
- PDA_THREAD_REG_STATE_ENTRY_FORMAT
