ci: Build more targets, cache SDKs, eatmydata

Build graph-depends and legal-info along with firmware images

Also, use proper O=/foo for telling buildroot where to build images.
Also, use the magic buildroot config script rather than hacky hacks.

Support building and caching an SDK, meaning you can build simple
defconfigs in dozens of minutes, and greatly reduce the total time
for building all configurations.

Eatmydata will save us a *lot* of fsync() activity when you don't
have infinite IOPS.

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.
