Change AST and AACRAID drivers to be modules instead of built-in

This patch changes the config files in order to make AST and AACRAID
drivers built as modules on Petitboot, instead of built-in.

Those drivers showed some issues lately that would've been
'workarounded' if both were modules, so we could blacklist
them. The total increase in BOOTKERNEL image is less than
80 kbytes.

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

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.
