This patch enables the multiple options in Options Vector5 which are
required and solves the boot issue 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.
