Add omap4 into omap3_defconfig. Note that this does not
yet boot on omap4, but boots on omap2 and omap3.

Also note that CONFIG_SMP does not currently work on
uniprocessor ARMs.

Move defines around and set up handlers based on MULTI_OMAP2.

Note that this will only allow compiling in omap4 with omap2 and
omap3. It will not yet make omap4 boot with multi-omap.

Note that booting 2420 depends on another patch posted earlier to not
select CONFIG_CPU_32v6K if CONFIG_ARCH_OMAP2 is selected.

Also note that we cannot add omap2430 in yet because of the different
clock addresses compared to 2420. Also note that we cannot have
CONFIG_CPU_32v6K=y in order to boot on 24xx.

Make get_irqnr_and_base common for mach-omap2 multiboot

Thanks to a tip from Russell King <rmk+kernel@arm.linux.org.uk>,
this also optimizes the code for non-multiboot configurations by
using get_irqnr_preamble.

Note that this will only work currently for 24xx and 34xx.
Support for 44xx can be added later on for basic multiboot,
and similar patch should be done for mach-omap1/entry-macro.S.

These are no longer needed. Note that zoom boards
should now set their own function in uncompress.h
and debug-macro.S for the external UART.

Define arch_decomp_setup() the same way as some other
architectures do. Use arch_id to configure the debug uart
based on the machine_is by storing it into the uart
scratchpad register for DEBUG_LL code to use.

This way we don't have conflicts with the defines
with compiling in multiple omaps. Set the addresses
for uarts in struct omap_globals for the early serial
init code.

Otherwise more complicated uart configuration won't be possible.
We can use r1 for tmp register for both head.S and debug.S.

NOTE: This patch depends on another patch to add the the tmp register
into all debug-macro.S files. That can be done with:

$ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/"

Currently the omap serial clocks are autoidled after 5 seconds.
However, this causes lost characters on the serial ports. As this
is considered non-standard behaviour for Linux, disable the timeout.

Note that this will also cause blocking of any deeper omap sleep
states.

To enable the autoidling of the serial ports, do something like
this for each serial port:

# echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout
# echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout
...

David Binderman ran the sourceforge tool cppcheck over the source code of the
new Linux kernel 2.6.33-rc6:

[./arm/mach-omap2/mux.c:492]: (error) Buffer access out-of-bounds

13 characters + 1 digit + 1 zero byte is more than 14 characters.

start using longer names.

3630 has more mux signals than 34xx. The additional pins
exist in omap36xx_cbp_subset, but are not initialized
as the superset is missing these offsets. This causes
the following errors during the boot:

mux: Unknown entry offset 0x236
mux: Unknown entry offset 0x22e
mux: Unknown entry offset 0x1ec
mux: Unknown entry offset 0x1ee
mux: Unknown entry offset 0x1f4
mux: Unknown entry offset 0x1f6
mux: Unknown entry offset 0x1f8
mux: Unknown entry offset 0x1fa
mux: Unknown entry offset 0x1fc
mux: Unknown entry offset 0x22a
mux: Unknown entry offset 0x226
mux: Unknown entry offset 0x230
mux: Unknown entry offset 0x22c
mux: Unknown entry offset 0x228

Fix this by adding the missing offsets to omap3 superset.
Note that additionally the uninitialized pins need to be
skipped on 34xx.

OMAP platforms(like OMAP3530) include DSP or other co-processors
for media acceleration. when carving out memory for the
accelerators we can end up creating a hole in the memory map
of sort:
<kernel memory><hole(memory for accelerator)><kernel memory>

To handle such a memory configuration ARCH_HAS_HOLES_MEMORYMODEL
has to be enabled. For further information refer discussion at:

Current behaviour is to generate the IT instruction only for Thumb-2
code. However, the kernel helpers in entry-armv.S are compiled to ARM in
a unified syntax file (if THUMB2_KERNEL). Recent compilers warn about
missing IT instruction in unified assembly syntax files. The patch
changes the "-mimplicit-it" gas option to "always".
