I do not think there was any particular reason. This was one of the few
ARM-based targets that are not armv5, however armv5 may have been used as a
template to kick the initial port.

If you want to submit a patch doing this, I will gladly apply it, we may
have to set a different FPU ABI between brcm2708 and 09 though.
