2017-08-11HDAT: Add chip-id property to ipmi sensorsVasant Hegde1-0/+36
Presently we do not have a way to map sensor to chip id. Hence we are always passing chip id 0 for occ_reset request (see occ_sensor_id_to_chip()). This patch adds chip-id property to sensors (whenever its available) so that we can map occ sensor to chip-id and pass valid chip-id to occ_reset request.

2017-06-16hw/phys_map: Use GCIDs as a chip indexOliver O'Halloran1-1/+1
Currently we pass in a proc_chip structure to phys_map_get(). All we we really need from this structure is the Global Chip ID (GCID). This patch reworks the function so that we only need to pass the GCID which allows us to use it before the proc_chip structures have been initialised (i.e in the HDAT parser).

2017-06-16hdata: Use GCID in LPC setupOliver O'Halloran1-2/+7
The HDAT has a notion of "chip ID" which is an arbitrary numbering of chips. This numbering isn't useful outside of the HDAT so we refer to chips uing their Global Chip ID (GCID). Currently we're using the HDAT chip ID in a few places and this patch fixes them. Signed-off-by: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2017-03-07hdat: Parse BMC nodes much earlierOliver O'Halloran1-1/+27
This moves the parsing of the BMC and LPC details to the start of the HDAT parsing. This allows us to enable the Skiboot log console earlier so we can get debug output while parsing the rest of the HDAT.

2017-03-03hdat: Fix interrupt & device_type of UART nodeBenjamin Herrenschmidt1-1/+3
The interrupt should use a standard "interrupts" property. The UART node also need a device_type="serial" property for historical reasons otherwise Linux won't pick it up.

2017-02-07lpc: Mark the power9 LPC bus as compatible with power8Benjamin Herrenschmidt1-1/+2
We support all the OPAL calls, and it avoids bugs in existing Linux kernels that would otherwise crash when attempting to access devices using a direct mapping. When Linux is fixed it will recognize that direct mapping is supported and avoid the OPAL calls.

2017-01-16hdat: Add BMC and LPC IOPATH supportOliver O'Halloran1-0/+163
BMC based systems use the LPC bus for communicating between the host and service processor. This is represented as a "SP IOPATH" in the HDAT and this patch adds parsing and generation of the devicetree entries to describe this.

2017-01-16hdat: Rework service procesor information parsingOliver O'Halloran1-51/+115
