7fa106116d Remove #include <machine/frame.h> from all the arm code that doesn't
really need it.  That would be almost everywhere it was included.  Add
it in a couple files that really do need it and were previously getting
it by accident via another header.

691dfc2d38 Enhance the Atmel SoC chip identification routines to account for more
SoC variants.  Fold the AT91SAM9XE chips into the AT91SAM9260
handling, where appropriate.  The following SoCs/SoC families are recognized:
	at91cap9, at91rm9200, at91sam9260, at91sam9261, at91sam9263,
	at91sam9g10, at91sam9g20, at91sam9g45, at91sam9n12, at91sam9rl,
	at91sam9x5
and the following variations are also recognized:
	at91rm9200_bga, at91rm9200_pqfp, at91sam9xe, at91sam9g45, at91sam9m10,
	at91sam9g46, at91sam9m11, at91sam9g15, at91sam9g25, at91sam9g35,
	at91sam9x25, at91sam9x35
This is only the identification routine: no additional Atmel devices
are supported at this time.

# With these changes, I'm able to boot to the point of identification
# on a few different Atmel SoCs that we don't yet support using the
# KB920X config file -- someday tht will be an ATMEL config file...

7670aa6951 Eliminate the now-unused AT91C_MASTER_CLOCK option and change the one
place in the source it was used to the more correct AT91C_MAIN_CLOCK.
Sort AT91C_MAIN_CLOCK into a better location in the options.arm file.

0a32ad9a42 Compute the master clock frequency, so we no longer need to have it
compiled into the kernel.  This allows us to boot the same kernel on
machines with different master clock frequencies, so long as we can
determine the main clock frequency accurately.  Cleanup the pmc clock
init function so it can be called in early boot so we can use the
serial port just after we call cninit.

# We have two calls to at91_pmc_clock_init for reasons unknown, that will
# be fixed later -- it is harmless for now.

d9369891ab Another minor re-arrangement of the code: calcualte the master clock
frequency in the at91_pmc_clock_init rather than passing it in.  Allow
for frequencies >= 21MHz by rounding to the nearest 500Hz (Idea from
Ian Lapore whose company uses a similar arrangement in their product).
at91_pmc_clock_init() is now nearly independent of the rest of the pmc
driver (which means we may be able to call it much earlier in boot
soon to eliminate the master clock config file requirement for printf
to work during early boot and also eliminate some interdependencies
with the device ordering which requires pmc to be the first device
added).

c72ac48503 Minor cleanup before some more major changes:
o main_clock_hz isn't used, eliminate it
o move main clock calculation code and table so we have only one ifdef.

460b10f523 Add support for the Atmel SAM9XE familiy of microcontrollers, which
consist of a ARM926EJ-S processor core with up to 512 Kbytes of on-chip
flash. Tested with SAM9XE512.

66d2871df6 - Try to bring these files closer to style(9).
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
