Subject: [PATCH 1/2] kern/ieee1275/init: Convert plain numbers to constants in
 Vec5

This patch converts the plain numbers used in Vec5 properties to constants.

1. LPAR: Client program supports logical partitioning and
   associated hcall()s.
2. SPLPAR: Client program supports the Shared
   Processor LPAR Option.
3. CMO: Enables the Cooperative Memory Over-commitment Option.
4. MAX_CPU: Defines maximum number of CPUs supported.

Subject: [PATCH 2/2] kern/ieee1275/init: Extended support in Vec5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
