Would this cause things in the kernel to automatically start using SRAM
found in device-tree, or would each use need to be added explicitly?
I'm just wondering if we might start seeing new bugs caused by firmware
using SRAM for special purposes but that memory not being properly
reserved or hidden from the kernel.
