Merge patch series "Move framebuffer reservation for SPL to RAM end"
Devarsh Thakkar <[email protected]> says:
Move video memory reservation for SPL at end of RAM so that it does
not interefere with reservations for next stage so that the next stage
need not have holes in between for passed regions and instead it can
maintain continuity in reservations.
Also catch the bloblist before starting reservations to avoid the same
problem.
While at it, also fill missing fields in video handoff struct before
passing it to next stage.
This is as per discussions at :
