TomR,
Any chance of you taking a look at these ARM MMU patches and either taking them in to u-boot/master or ACKing them so I can take them in via the Tegra repo?
So I know Albert was tacking a PR today and then ran into a bug with his Thumb-1 patchset. If they aren't in that PR then yes, I'll review/ack them but I suspect / hope Albert is taking a look and got side-tracked by the bug he found.
Thanks,
TomW

Please let me know when this series is in arm/master (or u-boot/master), as I need it to base Stephen's PCI/PCIe/XUSB patches on before I can send a PR for u-boot-tegra/master. 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.
Thanks,
Tom
