hostboot: enable use of ccache

We were missing the CCACHE part for the HB cross compiler, which
was meaning CCACHE wasn't getting invoked (if enabled) for building
hostboot.

With my "deterministic xml parsing" patch for Hostboot (not yet
upstream), this takes the time for re-compiling hostboot from 15 minutes
to less than 3 minutes (at least on this machine).

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.

  2. Enable Universe (Ubuntu only):

     sudo apt-get install software-properties-common
     sudo add-apt-repository universe
    
  3. 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 libxml2-dev libxml2-utils xsltproc \
       wget bc
    

Dependencies for 64-bit Fedora systems

  1. Install Fedora 25 64-bit (older Fedora should also work).

  2. Install the packages necessary for the build:
