Bump Skiboot to latest p10 version containing Big-Core patches
This pulls a new Skiboot with significant changes, maily focused on
Big-Core support. Summary of changes since 85b27f5:
Benjamin Herrenschmidt (7):
xive: Set the fused core mode properly
chip: Fix pir_to_thread_id for fused cores
cpu: Keep track of the "ec_primary" in big core more
direct-ctl: Use the EC primary for special wakeups
slw: Limit fused cores P9 to STOP0/1/2
cpu: Make cpu_get_core_index() return the fused core number
imc: Use pir_to_core_id() rather than cpu_get_core_index()
Cédric Le Goater (2):
xive/p10: configure XIVE for fused cores
xive/p10: Enforce thread enablement
Oliver O'Halloran (1):
fix the bonus cleanup_cpu_state()
Ryan Grimm (1):
Add basic P9 fused core support
Ryan P Grimm (1):
Merge pull request #26 from svaidyan/p10-fusedcore
Vaidyanathan Srinivasan (6):
Add POWER9 Cumulus processor PVR type
Add POWER9 Fleetwood platform support
Fused core support for P10
chip: fixes for fused cores on P10
xive/p10: add automatic Context Save and Restore support
Enable fused core mode support in OPAL

The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.
https://open-power.github.io/op-build/
See the doc/ directory for documentation source. Contributions are VERY welcome!
Issues, Milestones, pull requests and code hosting is on GitHub: https://github.com/open-power/op-build
See CONTRIBUTING.md for howto contribute code.
To build an image for a Palmetto system:
git clone --recursive git@github.ibm.com:open-power/op-build.git cd op-build ./op-build rainier_defconfig && ./op-build
There are also default configurations for other platforms in openpower/configs/. Current POWER8 platforms include Habanero, Firestone, and Garrison. Current POWER9 platforms include Witherspoon, Boston (p9dsu), Romulus, and Zaius.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
The machine your building on will need Python 2.7, GCC 6.2 (or later), and a handful of other packages (see below).
Install Ubuntu (>= 18.04) or Debian (>= 9) 64-bit.
Enable Universe (Ubuntu only):
sudo apt-get install software-properties-common sudo add-apt-repository universe
Install the packages necessary for the build:
sudo apt-get install cscope ctags libz-dev libexpat-dev \ python language-pack-en texinfo \ build-essential g++ git bison flex unzip \ libssl-dev libxml-simple-perl libxml-sax-perl libxml-parser-perl libxml2-dev libxml2-utils xsltproc \ wget bc rsync
Install Fedora (>= 25) 64-bit.
Install the packages necessary for the build:
sudo dnf install gcc-c++ flex bison git ctags cscope expat-devel patch \ zlib-devel zlib-static texinfo "perl(bigint)" "perl(XML::Simple)" \ "perl(YAML)" "perl(XML::SAX)" "perl(Fatal)" "perl(Thread::Queue)" \ "perl(Env)" "perl(XML::LibXML)" "perl(Digest::SHA1)" "perl(ExtUtils::MakeMaker)" \ libxml2-devel which wget unzip tar cpio python bzip2 bc findutils ncurses-devel \ openssl-devel make libxslt vim-common lzo-devel python2
