2017-05-26mem_region: rename HW_RESERVE to FW_RESERVEOliver O'Halloran1-3/+3
Currently all existing reservations are made by hostboot itself or on behalf of some other part of system firmware (e.g. the OCCs). We want to add a "true" hardware reservation type that should not be touched by the host OS. To prepare for that this patch renames the existing reservation type to refect it's actual usage.

2017-03-23homer : Enable HOMER region reservation for POWER9Shilpasri G Bhat1-8/+74
PBA BARs map various regions in HOMER memory used by STOP engines and OCC. Skip PBA BARs that have incomplete initialization and reserve the regions that are available in the system.

2015-08-17hw/homer: Don't re-reserve homer rangesJeremy Kerr1-5/+20
Hostboot is going to cover these ranges with its own reservations (to allow access from the HBRT image), so don't overwrite reservations with our own. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-06-05core/mem_region: Create reservations of type REGION_HW_RESERVEDskiboot-5.0.3Jeremy Kerr1-3/+3
All current users of mem_reserve are actually wanting HW_RESERVED memory; these reservations are for memory initialised pre-skiboot. This change marks these regions as REGION_HW_RESERVED instead of REGION_RESERVED. We also rename mem_reserve to mem_reserve_hw to reflect this change. This fixes an issue where the PRD daemon cannot find reserved ranges (eg, the homer image) that have been created by skiboot itself.

2014-12-01Add tweaks to work in Mambo simulatorBenjamin Herrenschmidt1-1/+1
Mambo doesn't implement various things such as PBA SCOMs, LPC, ChipTOD, etc... It also provides a special console hook. This adds detection of Mambo via the /mambo node, and enables us to boot all the way to Linux.

Having these in memory may be of benefit, but we don't need them out the serial console unless something fooey is going on. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
