Cover letter [PATCH 0/8] ppc64: Introduce Cell/BPA platform, v2
This series of patches add support for a fifth platform type in the ppc64 architecture tree. The Broadband Processor Architecture (BPA) is what machines using the Cell processor should be following and currently only prototype hardware exists for it.
Except for the last patch, these are functionally the same as the first version but are updated for 2.6.12-rc4 and contain changes based on the feedback I got so far.
The first three patches add some infrastructure that is used by BPA machines but is not really specific to them can could be used by other new platform types as well.
The next three patches add the actual platform code, which should be usable for any BPA compatible implementation.
Patch 7 introduces a new file system to make use of the SPUs inside the processors. This patch is still in a prototype stage and not intended for merging yet. The final patch adds some user space code in the Documentation directory that clarifies how to use the file system. This one should become a separate package at a later point.
