Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency.  While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board.  The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

Clean up added ehci-omap.c and make it generic for re-use across
omap-soc having same ehci ip block. Also pass the modes to be configured
from board file and configure the ports accordingly. All usb layers
are not cache aligned, till then keep cache off for usb ops as ehci will use
internally dma for all usb ops.

* Add a generic common header ehci-omap.h having common ip block
  data and reg shifts.
* Rename and modify ehci-omap3 to ehci.h retain only conflicting
  sysc reg shifts remove others and move to common header file.
* pass the board data for beagle/panda accordinly to use
  ehci ports.

TPS power IC is controlled using a GPIO (gpio_wk7).
This GPIO should be maintained at logic 1 always. As
such an internal pull-up on this pin will do the job,
driving the GPIO outuput is not needed. This will avoid
the need of using GPIO library in SPL and also may
save some power.

This patch adds the minimal support for OMAP5. The platform and machine
specific headers and sources updated for OMAP5430.

OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.

Also moved some part of code from the basic platform support that can be made
common for OMAP4/5. Rest is kept out seperately. The same approach is followed
for clocks and emif support in the subsequent patches.

Not all padconfs are the same between 4430 and 4460, so instead of
working around this with an if, we should have an specific padconf
structure for both chips (like handling the differences between the LEDs
GPIOs and TPS).

- separate mux settings into essential and non essential parts
- essential part is board independent as of now(so move it
  to SoC directory). Will help in having single SPL for all
  boards.
- Non-essential part(the pins not essential for u-boot to function)
  need to be phased out eventually.
- Correct mux data by aligning to the latest settings in x-loader

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

OMAP4 Panda is a reference board based on OMAP4430, an ARMV7 Cortex A9 CPU

This patch adds basic support for booting the board. It includes i2c and mmc
support. It assumes U-boot is loaded to SDRAM with the help of another small
bootloader (x-load) running from SRAM. U-boot currently relies on x-load for
clock, mux, and SDRAM initialization
