[Qemu-devel] [PATCH 07/15] e1000: Make little endian

[Alexander Graf]

The e1000 has compatibility code to handle big endianness which makes it
mandatory to be recompiled on different targets.

With the generic mmio endianness solution, there's no need for that anymore.
We just declare all mmio to be little endian and call it a day.

Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.
