That name should probably still be called harmony_something() since it's
still board-specific.

I wonder how having a per-board callback will integrate with device
tree. I guess I'll find out when I review patch 11:-)

You can remove that test now.

That's a somewhat odd place to put the header; a dedicated
mach-tegra/include/mach/tegra_pcie_pdata.h or
include/linux/platform_data/tegra_pcie.h might make more sense.

Aside from those pretty minor issues, this all looks great. Thanks for
fixing our driver!
