Hi all, This is the second time in my career that I've stumbled upon a SOC which has 32bit memory aliasing for high memory for the usage of drivers that can only address 32bit address space. Basically, a subset of a memory higher than 4GB can be accessed also through a range in the low 4GB addresses. I didn't see any support for this neither Linux kernel nor in device tree. I'm wondering if you considered adding a way to describe such addressing in the device tree, and maybe later Linux can add support for it. Thanks, Ramon
