ci: Get kernel version

When building with the SDK the build scripts have to specify the
kernel version (and GCC). This was hardcoded, which is fine as the CI
scripts are checked into the repo where the changes are made.

Hoover it's one more thing to remember when bumping the kernel version.
This grabs it from the BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE in the
given config file, which should always be set.

OpenPOWER Firmware Build Environment

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.

Documentation

https://open-power.github.io/op-build/

See the doc/ directory for documentation source. Contributions are VERY welcome!

Development

Issues, Milestones, pull requests and code hosting is on GitHub: https://github.com/open-power/op-build

See CONTRIBUTING.md for howto contribute code.

Building an image

To build an image for a Palmetto system:

git clone --recursive git@github.com:open-power/op-build.git
cd op-build
. op-build-env
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.

Dependencies for 64-bit Ubuntu/Debian systems

  1. Install Ubuntu (>= 14.04) or Debian (>= 7.5) 64-bit.
