istep 18.12 hb changes
18.12. host_coalesce_host : Re-activate Hostboot images
a) FSP sends each Hostboot image a mailbox .wakeup. message
This places an a pending interrupt to the EX, but it is
blocked by the .block wakeup. sources
b) FSP then removes the block wakeup sources (master processor last)
p8_block_wakeup_intr.C -reset
This removes the block wakeup sources and allows hostboot to
receive (and exit winkle) the pending mailbox message
c) HB instance will wake up (un-winkle) its master core, thread 0
d) Hostboot will then issue IPIs to all threads in its instance
e) Hostboot will establish IPC between each of the HB entities
On failure system will xstop or TI
No sync point with the FSP
