Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.

Move all the files named foo/common.c to foo/foo_common.c

Initial cut for DTS on the hl201 board.

Add commented out dts for sam9260ek as well as early printf support.

Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")

Set the baud rate if it isn't 0

Make at91_soc_id() public.

Properly round at91 resource on unmapping.

Move AT91 AIC related stuff to own file.

Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.

Follow r262916 with one more config file that references a renamed common.c

Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until
then...

Remove all dregs of a per-thread undefined-exception-mode stack.

Rework the VFP code that handles demand-based save and restore of state.

Always call vfp_discard() on thread death.

When a thread begins life it doesn't own the VFP hardware state on any cpu.

Make undefined exception entry MP-safe.

MFC r260695, r260696, r260884, r260885, r260886, r260887

Provide a simplified way to specify GPIO pins for the Atmel port.

Add at91 data so we can convert a PIO unit number into a base address.

Add at91 standard memory controller helper functions.

Generalize AT91 NAND support a bit.

Connect NAND for the SAM9260EK eval board, as well as the HotE HL-201.

Add nand device and NANDFS into the mix for those at91 boards that have
support for it at the moment.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Correct the PLLA setting functions and centralize.

Complete the transition away from newbus to populate the children to
the linker set of CPU modules. The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful. delay and cpu_reset now work much earlier in the
boot process.

Create the children devices for the SoC in atmelarm bus node, not in
the identify routine of the CPU.

Export the interrupt status vector via soc_data. Set the interrupt
priorities in the AIC in the atmelarm driver before attaching the
children. Delete redunant copies of the code.

Make the SoC stuff a little more modular, and start to move away from
having the CPU device that's a child of atmelarm that does stuff.

o Create a linker_set for the support fucntions for the SoCs.
o Rename soc_data to soc_info.
o Move the delay and reset function pointers to new soc_data struct
o Create elements for all known SoCs
o Add lookup of the SoC we found, and print a warning if it isn't one
we know about.

Go ahead and disable the interrupts for the DBGU the boot loader may
have left enabled after we detect the CPU, and remove the multiplely
copied code from the SoC modules.

Remove a useless bit of indirection. On all Atmel ARM products, irq 1
is the system IRQ, so use the define for it and get on with life.

Collapse all copies of at91_add_child into at91.c. They were
logically identical before today, and actually identical after today's
changes.

The system IRQ is always IRQ 1. Make it so.

Eliminate the AT91XXXX_BASE for each SoC. AT91_BASE is the right way
to spell this since we only have one AT91_BASE for all Atmel arm9 SoCs.

Strip trailing whitespace before other changes.

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...

Add support for the AT91SAM9260

Submitted by: Greg Ansley

if_ate.c:

* Support for sam9 "EMAC" controller.
* Support for rmii interface to phy.

at91.c & at91sam9.c:

* Eliminate separate at91sam9.c file.
* Add new devices to at91sam9_devs table.

at91_machdep.c & at at91sam9_machdep.c:

* Automatic chip type determination.
* Remove compile time chip dependencies.
* Eliminate separate at91sam9_machdep.c file.

at91_pmc.c:

* Corrected support for all of the sam926? and sam9g20 chips.
* Remove compile time chip dependencies.

My apologies to Greg for taking so long to take care of it.
