Move the saving of the auxiliary control registers into C; there's
no need for this to be in assembly code. This results in less
assembly code to deal with in OMAP.
Kevin tested full-chip retention and off on 3430/n900, 3530/Overo and
3630/Zoom3.

Most of the ASM sleep code (in arch/arm/mach-omap2/sleep34xx.S)
is copied to internal SRAM at boot and after wake-up from CORE OFF
mode. However only a small part of the code really needs to run from
internal SRAM.
This fix lets most of the ASM idle code run from the DDR in order to
minimize the SRAM usage and the overhead in the code copy.
The only pieces of code that are mandatory in SRAM are:
- the i443 erratum WA,
- the i581 erratum WA,
- the security extension code.
SRAM usage:
- original code:
. 560 bytes for omap3_sram_configure_core_dpll (used by DVFS),
. 852 bytes for omap_sram_idle (used by suspend/resume in RETention),
. 124 bytes for es3_sdrc_fix (used by suspend/resume in OFF mode on ES3.x),
. 108 bytes for save_secure_ram_context (used on HS parts only).
With this fix the usage for suspend/resume in RETention goes down 288
bytes, so the gain in SRAM usage for suspend/resume is 564 bytes.
Also fixed the SRAM initialization sequence to avoid an unnecessary
copy to SRAM at boot time and for readability.
Tested on Beagleboard (ES2.x) in idle with full RET and OFF modes.

Upon return from off-mode, the ROM code jumps to a restore function
saved in the scratchpad. Based on SoC revision or errata, this
restore entry point is different. Current code uses some helper
functions in sleep34xx.S (get_*_restore_pointer) to get the restore
function entry point.
When returning from off-mode, this code is executed from SDRAM, so
there's no reason to use these helper functions when using the SDRAM
entry points directly would work just fine.
This patch uses ENTRY/ENDPROC to create "real" entry points for these
functions, and uses those values directly when writing the scratchpad.
Tested all three entry points
- restore_es3: 3430/n900
- restore_3630: 3630/Zoom3
- restore: 3530/Overo

The code alludes to r9 being used to indicate what was lost over the
suspend/resume transition. However, although r9 is set, it is never
actually used.
Also, the comments before the code (which refer to the value of r9)
and the comments against the assignment of r9 contradict each other,
so just remove them to avoid confusion.

The ABI allows called functions to corrupt r0-r3 and ip (r12). So
its pointless saving these registers in the suspend code - the
calling function will expect them to be corrupted and so won't rely
on their contents after resume.

Replacing the hand-encoded instructions when the mnemonic also

*: 1. fncpy ensures that the thumb mode bit is propagated,

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
OMAP2xxx/3xxx-specific.
This process also requires the #includes in each of these files to be
changed to reference the new file name. As part of doing so, add some
comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
"sideways includes", to indicate that these users of the PRM/CM includes
should not be doing so.

While coming out of MPU OSWR/OFF states, L2 controller is reseted.
The reset behavior is implementation specific as per ARMv7 TRM and
hence $L2 needs to be invalidated before it's use. Since the
AUXCTRL register is also reconfigured, disable L2 cache before
invalidating it and re-enables it afterwards. This is as per
Cortex-A8 ARM documentation.
Currently this is identified as being needed on OMAP3630 as the
disable/enable is done from "public side" while, on OMAP3430, this
is done in the "secure side".

Erratum id: i608
RTA (Retention Till Access) feature is not supported and leads to device
stability issues when enabled. This impacts modules with embedded memories
on OMAP3630
Workaround is to disable RTA on boot and coming out of core off.
For disabling RTA coming out of off mode, we do this by overriding the
restore pointer for 3630 as the first point of entry before caches are
touched and is common for GP and HS devices. To disable earlier than
this could be possible by modifying the PPA for HS devices, but not for
GP devices.

Erratum i581 impacts OMAP3 platforms.
PRCM DPLL control FSM removes SDRC_IDLEREQ before DPLL3 locks causing
the DPLL not to be locked at times.
IMPORTANT:
*) This is not a complete workaround implementation as recommended
by the silicon erratum. This is a support logic for detecting lockups and
attempting to recover where possible and is known to provide stability
in multiple platforms.
*) This code is mostly important for inactive and retention. The ROM code
waits for the maximum DLL lock time when resuming from off mode. So for
off mode this code isn't really needed.
*) counters are introduced here for eventual export to userspace once the
cleanups are completed.
This should eventually get refactored as part of cleanups to sleep34xx.S

Analysis in TI kernel with ETM showed that using cache mapped flush
in kernel instead of SO mapped flush cost drops by 65% (3.39mS down
to 1.17mS) for clean_l2 which is used during sleep sequences.
Overall:
- speed up
- unfortunately there isn't a good alternative flush method today
- code reduction and less maintenance and potential bug in
unmaintained code
This also fixes the bug with the clean_l2 function usage.

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap. This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.
In response, move the SCM headers into mach-omap2/.
As part of this, remove the direct SCM access from the OMAP UDC
driver. It was clearly broken. The UDC code needs an indepth review for
use on OMAP2+ chips.

This patch adds a save and restore mechanism for ARM L2 auxiliary control
register. The feature is enabled by default for GP devices, but for HS/EMU
devices the user must enable the service and define the PPA service ID to
be used for setting L2 aux ctrl, as this is not currently supported by the
bootloader. If nobody alters the contents of L2 aux ctrl from its reset
value, this feature is not needed.

Kconfig option to select HS/EMU PPA service for setting L2 aux ctrl:
- OMAP3_L2_AUX_SECURE_SERVICE_SET_ID

The secure sram context save uses dma channels 0 and 1.
In order to avoid collision between kernel DMA transfers and
ROM code dma transfers, we need to reserve DMA channels 0
1 on high security devices.
A bug in ROM code leaves dma irq status bits uncleared.
Hence those irq status bits need to be cleared when restoring
DMA context after off mode.
There was also a faulty parameter given to PPA in the secure
ram context save assembly code, which caused interrupts to
be enabled during secure ram context save. This caused the
save to fail sometimes, which resulted the saved context
to be corrupted, but also left DMA channels in secure mode.
The secure mode DMA channels caused "DMA secure error with
device 0" errors to be displayed.

Following this will be a series of patches from the 'PM branch' of the
