POWER9 defconfigs: apply linux kernel patches

We initially disabled applying the patches on P9 platforms due to running
a more recent kernel on P9 than P8 configs (and it being early bringup).

Now that all platforms are on the same kernel, the patches will now apply.

So, enable linux kernel patches for our POWER9 platforms.

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.

Development

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

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/ 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.

Dependencies for 64-bit Ubuntu/Debian systems

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