Supporting the newer SM8550 and SM8650 SoCs unfortunately requires a bump in complexity for us. Qualcomm changed a lot about how the memory map is handed over to the "kernel", adding many holes, not mapping certain regions, and adding regions with 0 size. The SM8650 HDK has a whopping 14 memory regions, some as small as 44k.
Supporting this properly has proven to be a bit of a headache, but I think this implementation is "pretty good".

Applied, thanks!
