Looks like a PPC specific improvement, is it possible to have TPM on
other ARCHes? For generic code patch, Andrew kindly help pick them
into his tree if cooked. If it's an arch or component specific code,
we usually ask arch or component maintainer to take it.

For this patchset, it should be merged into ppc tree?
