[En-Nut-Discussion] anyone using SAM7S32?

[Bernd Walter]

Just tried to run ethernut the first time on a SAM7S controller.
My main function doesn't get excecuted it seems, so it looks to be
something in Ethernut startup.
I'd used the included st91sam7s32_rom.ld.

The tree was copied from a working SAM7X tree.
Some of the above definitions are leftovers.
Probably I missed to change something, but I don't see anything wrong.

All I can see so far is that the xtal starts oscillating, but main()
doesn't start.
