kern/ieee1275/init: Extended support in Vec5
This patch enables multiple options in Vec5 which are required and
solves the boot issues seen on some machines which are looking for
these specific options.
1. LPAR: Client program supports logical partitioning and
associated hcall()s.
2. SPLPAR: Client program supports the Shared
Processor LPAR Option.
3. DYN_RCON_MEM: Client program supports the
“ibm,dynamic-reconfiguration-memory” property and it may be
presented in the device tree.
4. LARGE_PAGES: Client supports pages larger than 4 KB.
5. DONATE_DCPU_CLS: Client supports donating dedicated processor cycles.
6. PCI_EXP: Client supports PCI Express implementations
utilizing Message Signaled Interrupts (MSIs).
7. CMOC: Enables the Cooperative Memory Over-commitment Option.
8. EXT_CMO: Enables the Extended Cooperative Memory Over-commit Option.
9. ASSOC_REF: Enables “ibm,associativity” and
“ibm,associativity-reference-points” properties.
10. AFFINITY: Enables Platform Resource Reassignment Notification.
11. NUMA: Supports NUMA Distance Lookup Table Option.
12. HOTPLUG_INTRPT: Supports Hotplug Interrupts.
13. HPT_RESIZE: Enable Hash Page Table Resize Option.
14. MAX_CPU: Defines maximum number of CPUs supported.
15. PFO_HWRNG: Supports Random Number Generator.
16. PFO_HW_COMP: Supports Compression Engine.
17. PFO_ENCRYPT: Supports Encryption Engine.
18. SUB_PROCESSORS: Supports Sub-Processors.
19. DY_MEM_V2: Client program supports the “ibm,dynamic-memory-v2” property in the
“ibm,dynamic-reconfiguration-memory” node and it may be presented in the device tree.
20. DRC_INFO: Client program supports the “ibm,drc-info” property definition and it may be
presented in the device tree.
