2015-11-13occ: hbrt: Change the OCC reset orderShilpasri G Bhat1-12/+28
Modify the OCC reset order such that master OCC is reset after the slave OCCs are reset. In Tuleta/Alpine systems 'proc0' will always be the master OCC, which has to be stopped last when FSP sends OCC_RESET command to Opal.

2015-05-07Preload VPD LID and set up fsp_lid_load() for async queued loadingStewart Smith1-3/+4
This means VPD LID is already loaded before we start preloading kernel and initramfs LIDs, thus ensuring VPD doesn't have to wait for them to finish being read from FSP. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2015-03-24Asynchronous LID/Resource loading for FSP systemsStewart Smith1-1/+1
This moves away from using fsp_sync_msg in fsp_fetch_data and instead using the platform hooks for start_preload_resource() to actually queue up a load and having the plumbing for checking if a resource is loaded yet. This gets rid of the "pollers called with locks held" warning we got heaps of previously. You can now boot some FSP systems without getting this warning at all. This also sets the stage for starting load of LIDs much earlier to when they're needed, improving boot time. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2014-11-25occ/hbrt: Call stopOCC() for implementing reset OCC command from FSPShilpasri G Bhat1-0/+29
OPAL is expected to leave OCC stopped after receiving reset OCC message from FSP. FSP will send this either at boot before a load/start, or during runtime before load/start. If there is no subsequent load/start command, the OCC can be left stopped. After few attempts (runtime reset), FSP can just send reset and expect OPAL to leave OCC in stopped state. Call HBRT to stop OCC on FSP reset OCC command and acknowledge.
