sysvpd: Add UUID property
|
|
|
482a8d7 |
|
|
|
482a8d7 |
Recent LPARs contains "ibm,partition-uuid" device tree property.. which
|
|
|
482a8d7 |
is unique UUID for each LPAR. This is represented by `MU` keyword.
|
|
|
482a8d7 |
|
|
|
482a8d7 |
Lets add support to parse this property and populate vpddb.
|
|
|

|
|
|
482a8d7 |
Ideally we should enhance libvpd to support new keyword. But that will
|
|
|
482a8d7 |
add depedency on libvpd version. Hence adding this new keyword (MU)
|
|
|
482a8d7 |
as DeviceSpecific keyword.
