2020-01-29npu2, npu3: Remove ibm, phb-index property from the NPU dt nodeFrederic Barrat1-1/+0
The 'ibm,phb-index' property of the NPU node is now useless, as we can have multiple PHBs associated to the same NPU on P9. Let's remove it to avoid confusion.

2019-12-16doc/imc: Fix sphinx warningOliver O'Halloran1-1/+3
Using a normal :: block results in "WARNING: Unexpected indentation." I don't know why, but replacing it with a plain-text code block cures it. Signed-off-by: Oliver O'Halloran <oohall@gmail.com>
2019-12-16doc: Fix some errors in platforms-and-cpusOliver O'Halloran1-9/+23
Apollo was a P7 platform, not P8, and we don't support P7 any more. VESNIN is a P8 platform. Garrison uses the P8NVL chip, few other minor mistakes. There's stilll a bunch of systems missing from here, but eh. I also added a note about P7 support being dropped. Signed-off-by: Oliver O'Halloran <oohall@gmail.com>

2019-12-16doc: Use parallel buildsOliver O'Halloran1-1/+1
Using all your cores makes re-building the documentation a significantly faster. It'd be even faster if sphinx would stop assuming every single .rst file changes between builds, but casual googling didn't reveal a fix so -EEFFORT. Might be a bug in Sphinx 1.8.3 which Fedora is shipping. Signed-off-by: Oliver O'Halloran <oohall@gmail.com>

2019-12-16doc: Fix code blocks in v6.3.3 release notesOliver O'Halloran1-3/+6
Sphinx seems to choke if there's an additional indentation in a :: block. e.g.: :: one two three four It'll complain about the indentation changing at three. A ".. code-block:: text" block doesn't seem to have this problem so use that instead. Also note that you need a blank line between the code-block and the start of the actual code block.

2019-12-16add little endian supportNicholas Piggin1-1/+1
This adds support for building LE skiboot with LITTLE_ENDIAN=1. This is not complete, notably PHB3, NPU* and *CAPI*, but it is sufficient to build and boot on mambo and OpenPOWER POWER9 systems. LE/ELFv2 is a nicer calling convention, and results in smaller image and less stack usage. It also follows the rest of the Linux/OpenPOWER stack moving to LE. The OPALv3 call interface still requires an ugly transition through BE for compatibility, but that is all handled on the OPAL side.

2019-12-05secvar_devtree: add generic compatible, and new format device tree propertyEric Richter1-1/+20
This patch adds a generic compatible entry to the secvar/compatible device tree property for kernels, etc to match for basic secvar information (e.g. the linux secvar-sysfs implementation). The new "format" property exposes the expected format for data passing in and out of the secvar API. In most cases, this should be the same as the backend-specific compatible entry.

2019-08-02occ: Add pstate corresponding to base frequency to DTShilpasri G Bhat1-1/+11
Unlike POWER8, nominal frequency is not the highest guaranteed frequency of the POWER9 chip. In POWER9, the highest guaranteed frequency is greater than the nominal frequency and is referred to as base frequency. In POWER9 base frequency is the highest frequency the processor will operate at when ALL cores are active and in ANY operating condition. This patch exports the turbo pstate as the base frequency as per OCC documentation.
