[Skiboot] Skiboot 5.0.5 released

[Stewart Smith]

Hi all,

I just tagged skiboot-5.0.5, with one backported fix that some vendors
of OpenPower machines with an AMI BMC have been carrying:

commit f5a7c43a163f5484d2bd2b8b74814abc23f1e92d

    bt: Remove B_BUSY state

    The bt layer used to cache the value of B_BUSY in the state machine,
    assuming that once B_BUSY was cleared by the BMC that it would never
    be set by the BMC again unless a message was sent to the bt interface.

    This was mostly true for the AMI firmware except when the BMC reboots
    which causes B_BUSY to be set. There may also be additional
    circumstances which set B_BUSY. Therefore the bt layer must check
    B_BUSY is clear before sending a message making the B_BUSY state
    superfluous.


This is headed for op-build v1.5
