Laurent Pinchart 3794705aeb ARM: shmobile: Select CONFIG_ZONE_DMA when CONFIG_ARM_LPAE is enabled 
Most IP cores on ARM Renesas platforms can only address 32 bits of
physical memory for DMA. Without CONFIG_ZONE_DMA enabled and with the
recent CMA highmem allocation support, the default CMA zone is reserved
above the 4GiB limit when LPAE is enabled, resulting in various driver
failures.

Fix the problem by selecting CONFIG_ZONE_DMA. Other options to
investigate in the future would be to either enable IOMMU support or use
custom CMA reservations for peripherals not supporting LPAE.

While not a strict dependency, the "[PATCH 0/4] Low/high memory CMA
reservation fixes" series is also required to fix a different but related CMA
allocation problem.
