This patch adds an OPAL console backend to the powerpc boot wrapper so that decompression failures inside the wrapper can be reported to the user. This is important since it typically indicates data corruption in the firmware and other nasty things. Currently this only works when building a little endian kernel. When compiling a 64 bit BE kernel the wrapper is always build 32 bit to be compatible with some 32 bit firmwares. BE support will be added at a later date. Another limitation of this is that only the "raw" type of OPAL console is supported, however machines that provide a hvsi console also provide a raw console so this is not an issue in practice.
