5-8-4 Intel UPI POST Codes
When system BSP tries to setup path for remote sockets
or sends a Boot_Go command to remote socket in
SetupSbspPathToAllSockets() or SyncUpPbspForReset().
If the remote socket(s) hasn't checked-in, assert; it is a
fatal condition, this error will be logged. No retry.
RC Behavior: System Halt
0xD8
When SBSP tries to add this remote socket into system
topology tree in SetupSbspPathToAllSockets(), there
are some errors occur in the data structure.
No retry.
RC Behavior: The current Socket is not added to the tree.
When SBSP setups the boot path for the parent which is not
directly connected to Legacy CPU in SetupSbspPathToAllSockets().
The Child is not an immediate neighbor of Parent.
No retry.
