[Barrelfish-users] Barrelfish arm_gem5

[Daniel Röhrig]

Hi Samuel,

we are targeting ARMv5 and we are using qemu for testing so we are going
to stick with the normal arm-port. Our goal is to get barrelfish
running on our portuxg20-boards (with an arm926ej-s cpu). Thanks for
your explanation.

Best regards
Daniel
