This patch adds support for the Wave521cl on the AM62P. The node requires an SRAM buffer to reduce bandwidth by saving temporal information. Can only allocate 62KB for this given there is only 64 KB SRAM available on AM62P. Wave521cl needs to use CMA as there is no IO MMU on AM62P. Allocate 544 MB of CMA to meet 12 channel 720x480 use-case for this device.
