OMAP3430ES2+ introduces a new feature: optional powerdomain context
hardware save-and-restore (SAR).  Currently, this feature only applies
to USBHOST and USBTLL module context when the USBHOST or CORE
powerdomains enter a low-power sleep state[1].  This feature avoids
re-enumeration of USB devices when the powerdomains return from idle,
which is potentially time-consuming.

This patch adds support for enabling and disabling hardware
save-and-restore to the powerdomain code.  Three new functions are
added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and
pwrdm_can_hdwr_sar().  A new struct powerdomain "flags" field is
added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with
SAR support.

Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an
earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com>
for clarifying the purpose of these bits.

1.  For the USBHOST controller module, context loss occurs when the
    USBHOST powerdomain enters off-idle.  For USBTLL, context loss
    occurs either if CORE enters off-idle, or if the CORE logic is
    configured to turn off when CORE enters retention-idle (OSWR).

This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code:

1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c.

2) i variable is only used when compiling for big endian.
So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.

This patch integrates the OMAP3 clock tree with the clockdomain code.
This patch:

- marks OMAP34xx clocks with their corresponding clockdomain.

- adds code to convert the clockdomain name to a clockdomain pointer in the
  struct clk during clk_register().

- modifies OMAP2 clock usecounting to call into the clockdomain code
  when clocks are enabled or disabled.

This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

The patch also adds clockdomain usecount tracking.  This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled.  If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain.  If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.

Each clockdomain will be defined in later patches as static
structures.  The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

With gcc 4.3 and later, a pointer that has already been dereferenced is
assumed not to be null since it should have caused a segmentation fault
otherwise, hence any subsequent test against NULL is optimized away.

Current inline asm constraint used in the implementation of prefetch()
makes gcc believe that the pointer is dereferenced even though the PLD
instruction does not load any data and does not cause a segmentation
fault on null pointers, which causes all sorts of interesting results
when reaching the end of a linked lists for example.

Let's use a better constraint to properly represent the actual usage of
the pointer value.

This patch will truncate and/or ignore memory banks if their kernel
direct mappings would (partially) overlap with the vmalloc area or
the mappings between the vmalloc area and the address space top, to
prevent crashing during early boot if there happens to be more RAM
installed than we are expecting.

Since the start of the vmalloc area is not at a fixed address (but
the vmalloc end address is, via the per-platform VMALLOC_END define),
a default area of 128M is reserved for vmalloc mappings, which can
be shrunk or enlarged by passing an appropriate vmalloc= command line
option as it is done on x86.

On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000,
two 512M RAM banks and vmalloc=128M (the default), this patch gives:

	Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap).
	Memory: 512MB 352MB = 864MB total

On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000,
two 256M RAM banks and vmalloc=768M, this patch gives:

	Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap).
	Ignoring RAM at 10000000-1fffffff (vmalloc region overlap).
