272489fe59 Pass the previously returned IRQ back to arm_get_next_irq() so that
the implementation can guarantee forward progress in the event of
a stuck interrupt or interrupt storm. This is especially critical
for fast interrupt handlers, as they can cause a hard hang in that
case. When first called, arm_get_next_irq() is passed -1.

f3bdbeccf7 - Add the driver for AT91RM9200 CompactFlash controller. The driver
operates in the common memory mode and use polling mode to control
  the status of operations as I don't have any board with interrupt
  line routed yet. I'll add the GPIO interrupt driven mode as soon
  as I get one.

5d5516e7b7 Store at91_master_clock in a global variable as opposed to a compile
time constant.  This allows us to potentially change it at runtime or
autodetect it early in the boot (the latter being much more likely to
have a good outcome).

e704206e27 Kill vestiges of the special case code we once had in place for usb
memory allocation.  It was change to include the range in the normal
memory area, so these ifdef'd out special cases are no longer useful
to keep around.

5d8e2080ac Add IRQ line for usb device. I'm not 100% sure this is the right
place to add this connection, since the interrupt is for a GPIO pin,
but since we have no alternative at the moment...

e19357d3a5 On the AT91, we need to write on the EOI register after we handle an
interrupt. So, add a new function pointer, arm_post_filter, which defaults
to NULL, and which will be used as the post_filter arg for
intr_event_create(). Set it properly for the AT91, so that it boots again.

1981bc3b8a Actually program the interrupt controller for priorities. As we
support more AT91 platforms, we'll need to move this into some
platform init routine.

d5d776c16b Resurrect Skyeye support :
Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds
workarounds for things skyeye doesn't simulate. Specifically :
- Use USART0 instead of DBGU as the console, make it not use DMA, and           manually provoke an interrupt when we're done in the transmit function.
- Skyeye maintains an internal counter for clock, but apparently there's
no way to access it, so hack the timecounter code to return a value which
is increased at every clock interrupts. This is gross, but I didn't find a
better way to implement timecounters without hacking Skyeye to get the
counter value.
- Force the write-back of PTEs once we're done writing them, even if they
are supposed to be write-through. I don't know why I have to do that.

1248f2322b Import support for the Atmel AT91RM9200 CPU/Microcontroller. This SoC
is a ARM920T based CPU with a bunch of built-in peripherals.  The
inital import supports the SPI bus, the TWI bus (although iicbus
integration is not complete), the uarts, the system timer and the
onboard ethernet.  Support for the Kwikbyte KB9202
(http://www.kwikbyte.com) board is also included, although there's no
reason why the 9200 and the 9201 wouldn't also work.  Primitive
support for running under the skyeye emulator is also provided
(although skyeye's support for the AT91RM9200 is a little weak).

The code has been structured so that other members of Atmel's arm family can
be supported in the future.  The AT91SAM9260 is not presently supported
due to lack of hardware.  The arm7tdmi families are also not supported
becasue they lack an MMU.

Many thanks to cognet@ for his help and assistance in bringing up this
board.  He did much of the vm work and wrote parts of the uart and
system timer code as well as the bus space implementation.

The system boots to single user w/o problem, although the serial
console is a little slow and the ethernet driver is still in flux.

This work was sponsored by Timing Solutions, Corporation.  I am
grateful to their support of the FreeBSD project in this manner.
