[Qemu-devel] mach-virt RAM start address

[Giridhar Maruthy]

Hi,

I am using mach-virt in qemu which boots correctly when RAM start
address is 0x8000000. But if I change the address to anything like
0x9000000, the mach-virt machine just hangs, not even an error
message.

Do we have to mention the RAM start address anywhere else?
