[ Upstream commit 632c99084052aef1c9dcfe43d2720306026d6d21 ]
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.
