qemu-e2k/hw/arm/versatilepb.c
Andreas Färber 8a661aea0e Revert use of DEFINE_MACHINE() for registrations of multiple machines 
The script used for converting from QEMUMachine had used one
DEFINE_MACHINE() per machine registered. In cases where multiple
machines are registered from one source file, avoid the excessive
generation of module init functions by reverting this unrolling.
