Subject: [PATCH] of: of_reserved_mem: Increase limit on number of reserved regions
Date:   Mon, 24 Feb 2020 10:02:32 -0800
Message-Id: <1582567352-4664-1-git-send-email-isaacm@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org

From: Patrick Daly <pdaly@codeaurora.org>

Certain SoCs need to support a large amount of reserved memory
regions. For example, Qualcomm's SM8150 SoC requires that 20
regions of memory be reserved for a variety of reasons (e.g.
loading a peripheral subsystem's firmware image into a
particular space).

When adding more reserved memory regions to cater to different
usecases, the remaining number of reserved memory regions--12
to be exact--becomes too small. Thus, double the existing
limit of reserved memory regions.
