ARM: tegra: fix DEBUG_LL combined with LPAE
The DEBUG_LL UART address is mapped as an MMU section, hence, the virtual address must be section-aligned. Sections are 1MB without LPAE and 2MB with LPAE. Tegra's virtual address was only aligned to 1MB, and hence the mapping was set up incorrectly with LPAE enabled, thus causing a hang early during boot. Fix this by picking a different virtual address that is aligned to 2MB. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Thierry Reding <treding@nvidia.com>
