Subject: [PATCH] ARM: tegra: Select appropriate DMA options for LPAE

This automatically selects options for zone DMA and 64 bit DMA addresses
when LPAE is enabled on ARM Tegra platforms. These options are required
for proper operation with LPAE enabled.

Bumping this one since it did not get any review yet.

It should be a good candidate for inclusion now that the merge window is open.

If you don't get any reply still, send it to the ARM SoC maintainers
directly at [email protected] and request it to be applied.
