[PATCH 0/4] Add global CMA areas for few TI SoCs

[Jayesh Choudhary]

Hello All,

Following AM62* platforms[0], this patches add global CMA reserve area for:
- J721S2-EVM (1056 MiB)
- J784S4-EVM (1920 MiB)
- AM68-SK (1008 MiB)
- AM69-SK (1904 MiB)

These SoCs does not have MMU and hence they require contiguous memory
pool to support various multimedia usecase.

The calculation was done considering H264 codec requirements, dual-display
supported in each platforms and multicamera use-cases.
Additional buffer was kept for other peripheral s and to account for
fragmentation.
The breakdown is mentioned in each commit message.
