VERSION: Improve logic behind and information in VERSION partition The VERSION partition is constructed in pkg-versions.mk, and has the purpose of indicating to both the user and developer/support what firmware build is on a particular machine. This patch addresess a few issues with VERSION. Firstly, the pkg-versions.mk code was making needlessly excessive calls to git, which could be solved by using "git describe --always --dirty" rather than going around and around. Secondly, the information in VERSION was not always useful. Previously, we'd get an entry like 'open-power-habanero-78d8928', which is only useful if you posses a tree with that commit in it. With this patch, instead you get 'open-power-habanero-v1.14-45-g78d89280c3f9' which tells us a *lot* more information about what was used to build this image. The same issue was with buildroot (was: 'buildroot-6b9fd80', now: 'buildroot-2016.11-4-g6b9fd8036d72') Thirdly, the (truncated) SHA512 hash of the patches to a package was not always clear that it was a SHA of patches. We now prefix the patch sha with a 'p' (Git prefixes a sha with a 'g'). For example: 'habanero-xml-6a78496-67a075c' becomes 'habanero-xml-6a78496-p67a075c' Fourthly, the version targets threw some shell errors, so they're also fixed.

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.

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/ such as Habanero and Firestone.
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.
