I am not sure if any of the DaVinci devices have a need to allocate from
*both* ARM RAM and shared RAM. Shared RAM is not present on all DaVinci
devices AFAIR, and on DA850, there is just 8KB ARM RAM so I am not sure
if there is much point in trying to allocate from there.

Can you instead see if Ben's earlier patch[1] to use shared RAM for SRAM
allocation on DA850 makes sense for your case? If yes, can you repost
with Ben's patch included in your series instead of this patch? I would
prefer that over creating a new pool for shared RAM.
