For ARMv7 you can only really use 2047MB of RAM with the memory map we have in the simulator. It would be possible to use more with the LPAE extensions we recently implemented, but it would certainly required some work on your part to define a new memory map and modify a dtb file appropriately. For ARMv8 it’s much easier to get more RAM, however it too doesn’t work outside the box. To make this work you need to again modify a DTB file and the armv8 boot loader start address to match that address. I’ve got the latter mostly working and will try to get you some instructions in the next week.
