kernel: Move to Linux v5.3.5-openpower1 This adds Firmware Assissted dump passthrough mode to the OpenPower kernel. These patches were backported from 5.4, and the CONFIG_PRESERVE_FA_DUMP was added. PowerPC related changes: powerpc: dump kernel log before carrying out fadump or kdump powerpc/eeh: Clean up EEH PEs after recovery finishes powerpc/64s/exception: machine check use correct cfar for late handler powerpc/eeh: Clear stale EEH_DEV_NO_HANDLER flag powerpc/perf: fix imc allocation failure handling powerpc/64s/radix: Fix memory hotplug section page table creation powerpc/futex: Fix warning: 'oldval' may be used uninitialized in this function powerpc/ptdump: fix walk_pagetables() address mismatch powerpc/rtas: use device model APIs and serialization during LPM powerpc/xmon: Check for HV mode when dumping XIVE info from OPAL powerpc/powernv/ioda2: Allocate TCE table levels on demand for default DMA window powerpc/imc: Dont create debugfs files for cpu-less nodes powerpc/Makefile: Always pass --synthetic to nm if supported powerpc/xive: Fix bogus error code returned by OPAL Signed-off-by: Joel Stanley <joel@jms.id.au>
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.

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.com:open-power/op-build.git cd op-build ./op-build palmetto_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-bignum "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
