[Qemu-ppc] [PULL 20/26] hw/ppc: deprecate the machine type 'prep', replaced by '40p' |

From: Hervé Poussineau <address@hidden>
- prep machine is a fictional machine, so has no specifications. Which
devices can be changed/added/removed without impact? Are interrupts
correctly mapped?
- prep firmware (OHW) has support only for IDE drives (no SCSI).
Booting from IDE has been broken approximatively 3 years ago, and nobody
complained.
- OHW is limited on IDE boot to a specific set of OS loaders.
These operating systems are of the 2004 time frame.
- OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse
detection, and then screen becomes garbage. This was already broken in
QEMU v2.7, 2 years ago, and nobody complained.
On the other side:
- 40p is a real machine, so emulation can be checked against
hardware specifications
- OpenBIOS has support for SCSI block devices, including 40p LSI adapter
- OpenBIOS can start mostly all Linux kernels (including recent ones)
and recent operating system (like NetBSD 7.1.2)
