[PATCH] ppc64: add BPA platform type
This adds the basic support for running on BPA machines. So far, this is only the IBM workstation, and it will not run on others without a little more generalization. It should be possible to configure a kernel for any combination of CONFIG_PPC_BPA with any of the other multiplatform targets.
