Thanks! I need this patchset in before I can add Stephen's PCIe/XUSB patchsets to Tegra U-Boot.
If you can Ack them, I can take them in via the Tegra repo, and send them upstream to TomR on my next PR. Or if you can let me know an ETA for getting them in to the ARM/master repo, I can base my schedule off of that. But I'm blocked until the ARMv8 MMU changes are in somewhere, and I'd like to clear this from my plate.
