[PATCH 6/9] ARM: tegra: Support multiple reserved memory regions

Fri Sep 3 15:16:22 CEST 2021
From: Thierry Reding <treding at nvidia.com>
Support multiple reserved memory regions per device to support platforms
that use both a framebuffer and color conversion lookup table for early
boot display splash.
While at it, also pass along the name, compatible strings and flags of
the carveouts.
