Subject: [PATCH 0/9] arm64: dts: qcom: msm8916/39: Reserve firmware memory
 dynamically

Refactor the MSM8916 and MSM8939 device trees to make use of dynamic 
memory reservations for the firmware regions, rather than hardcoding 
fixed addresses for each device. This allows to keep most of the 
definitions in the SoC.dtsi while defining the board-specific 
properties (such as firmware size) separately for each device.

The main motivation for this patch set is to simplify enabling the 
modem on the various MSM8916/39 devices. The modem firmware size 
differs on almost each device, which requires redefining *all* of
the firmware reservations with newly calculated addresses to make
room for the larger modem firmware. I've explained this in detail
in a previous RFC:
