Hi; this is a pretty common question, which we talk about on our
wiki page here:
 https://wiki.qemu.org/Documentation/Platforms/ARM

The underlying reason why you need this on Arm but not on x86
is that for x86 every single piece of x86 hardware is pretty
much identical. For Arm (as part of its history in the embedded
space) the general rule is that every board is different.
