[Qemu-devel] [PATCH 0/9] Don't use ld./st._phys in hw/

[Alexander Graf]

We have quite some code in hw/ that uses ld./st._phys functions
in device emulation code. This is just pure wrong, as devices
don't know about the CPU endianness (except for virtio), so they
should instead use something endian specific.

Unfortunately, there is no endian specific call to easily receive
an integer from memory, so this patch set introduces some and then
converts all the obvious users to them.

I tested the targets I could, but please double-check if your
architecture behaves differently or I accidently put in a _be
instead of _le :)
