Adds the flag 'recvSnoops' which enables pagewalkers using DmaPorts,
to properly configure snoops.

There was a bug in the mm_disk implementation where a copy paste error
resulted in the d32 variable not being initialised (as it incorrectly
was used instead of d16), and gcc 4.5 complaining.

Make DmaDevice::getPort() call PioDevice::getPort() instead
of just copying and pasting the code.
Also move definitions from .hh to .cc file.

'tickEvent' was not being serialized as in its place 'event' was being used.
This patch rectifies this error.

This is so they don't have to declare themselves to the IO APIC and don't have
to have a pointer to the platform object.

Not all objects need a platform pointer, and having one creates a dependence
on their being a platform object. This change removes the platform pointer to
from the base device object and moves it into subclasses that actually need
it.

In order for a system object to work in SE mode and FS mode, it has to either
always require a platform object even in SE mode, or get rid of the
requirement all together. Making SE mode carry around unnecessary/unused bits
of FS seems less than ideal, so I decided to go with the second option. The
platform pointer in the System class was used for exactly one purpose, a path
for the Alpha Linux system object to get to the real time clock and read its
frequency so that it could short cut the loops_per_jiffy calculation. There
was also a copy and pasted implementation in MIPS, but since it was only there
because it was there in Alpha I still count that as one use.
This change reverses the mechanism that communicates the RTC frequency so that
the Tsunami platform object pushes it up to the AlphaSystem object. This is
slightly less specific than it could be because really only the
AlphaLinuxSystem uses it. Because the intrFrequency function on the Platform
class was no longer necessary (and unimplemented on anything but Alpha) it was
eliminated.
After this change, a platform will need to have a system, but a system won't
have to have a platform.

Initialize flags via the Event constructor instead of calling
setFlags() in the body of the derived class's constructor. I
forget exactly why, but this made life easier when implementing
multi-queue support.
Also rename Event::getFlags() to isFlagSet() to better match
common usage, and get rid of some unused Event methods.

Some DPRINTFs were printing uninitalized values because the DPRINTFs were
always being printed even when the features they were printing weren't
being used. This change moves the DPRINTFs into the appropriate if blocks
and initializes the state variables correctly.
There also is a case where the offset into the packet could be calculated
incorrectly during a DMA that is fixed.

The driver can read the IDE config register as a 32 bit register since
some adapters use bit 18 as a disable channel bit. If the size isn't
set in a PRD it should be 64K according to the SPEC (and driver) not
128K.

Cortex-A9 processors can have a local timer and watchdog counter. It
is enabled by default in Linux and up to this point we've had to disable
them since a model wasn't available. This change allows a default
MP ARM Linux configuration to boot.

A significant contributor to the need for adoptOrphanParams()
is the practice of appending to SimObjectVectors which have
already been assigned as children. This practice sidesteps the
assignment operation for those appended SimObjects, which is
where parent/child relationships are typically established.
This patch reworks the config scripts that use append() on
SimObjectVectors, which all happen to be in the x86 system
configuration. At some point in the future, I hope to make
SimObjectVectors immutable (by deriving from tuple rather than
list), at which time this patch will be necessary for correct
operation. For now, it just avoids some of the warning
messages that get printed in adoptOrphanParams().

Add registers and components to better support the VersatileEB board.
Made the MIDR and SYS_ID register parameters to ArmSystem and RealviewCtrl
respectively.

At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing. This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

non-cache.
This change fixes the problem for all the cases we actively use. If you want to try
more creative I/O device attachments (E.g. sharing an L2), this won't work. You
would need another level of caching between the I/O device and the cache
(which you actually need anyway with our current code to make sure writes
propagate). This is required so that you can mark the cache in between as
top level and it won't try to send ownership of a block to the I/O device.
Asserts have been added that should catch any issues.

The timer calculations were a bit off so time would run faster than
it otherwise should
