Add support for the Motorola/Emerson MVME5100 Single Board Computer.
The MVME5100 is a 6U form factor VME64 computer with:
- A single MPC7410 or MPC750 CPU
- A HAWK Processor Host Bridge (CPU to PCI) and
MultiProcessor Interrupt Controller (MPIC)
- Up to 500Mb of onboard memory
- A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip
- Two 16550 compatible UARTS
- Two Intel E100 Fast Ethernets
- Two PCI Mezzanine Card (PMC) Slots
- PPCBug Firmware
The HAWK PHB/MPIC is compatible with the MPC10x devices.
There is no onboard disk support. This is usually provided by installing a PMC
in first PMC slot.
This patch revives the board support, it was present in early 2.6
series kernels. The board support in those days was by Matt Porter of
MontaVista Software.
CSC Australia has around 31 of these boards in service. The kernel in use
for the boards is based on 2.6.31. The boards are operated without disks
from a file server.
This patch is based on linux-3.13-rc2 and has been boot tested.
Only boards with 512 Mb of memory are known to work.

If we want to stop the tick further idle, we need to be
able to account the cputime without using the tick.
Virtual based cputime accounting solves that problem by
hooking into kernel/user boundaries.
However implementing CONFIG_VIRT_CPU_ACCOUNTING require
low level hooks and involves more overhead. But we already
have a generic context tracking subsystem that is required
for RCU needs by archs which plan to shut down the tick
outside idle.
This patch implements a generic virtual based cputime
accounting that relies on these generic kernel/user hooks.
There are some upsides of doing this:
- This requires no arch code to implement CONFIG_VIRT_CPU_ACCOUNTING
if context tracking is already built (already necessary for RCU in full
tickless mode).
- We can rely on the generic context tracking subsystem to dynamically
(de)activate the hooks, so that we can switch anytime between virtual
and tick based accounting. This way we don't have the overhead
of the virtual accounting when the tick is running periodically.
And one downside:
- There is probably more overhead than a native virtual based cputime
accounting. But this relies on hooks that are already set anyway.
