Increase the console I/O buffer size (SYS_CBSIZE) to 512 (from 256)
required especially for bootargs string, as multiple options
(e.g Video settings) are passed to the kernel through bootargs.

- Add MMC raw and FAT mode boot support for OMAP
- Provide a means by which parameters passed by ROM-code
can be saved in u-boot.
- Save boot mode related information passed by OMAP4 ROM-code
and use it to determine where to load the u-boot from
- Assumes that the image has a mkimage header. Gets the
payload size and load address from this header. If the
header is not detected assume u-boot.bin as payload

Identify SDRAM devices connected to EMIF automatically:
LPDDR2 devices have some Mode Registers that provide details
about the device such as the type, density, bus width
etc. EMIF has the capability to read these registers. If there
are no devices connected to a given chip-select reading mode
registers will return junk values. After reading as many such
registers as possible and matching with expected ranges of
values the driver can identify if there is a device connected
to the respective CS. If we identify that a device is connected
the values read give us complete details about the device.
This along with the base AC timings specified by JESD209-2
allows us to do a complete automatic initialization of
SDRAM that works on all boards.
Please note that the default AC timings specified by JESD209-2
will be safe for all devices but not necessarily optimal. However,
for the Elpida devices used on Panda and SDP the default timings
are both safe and optimal.

Calculate EMIF register values based on AC timing parameters
from the SDRAM datasheet and the DDR frequency rather than
using the hard-coded values.
For a new board the user doen't have to go through the tedious
process of calculating the register values. Instead, just
provide the AC timings from the device data sheet as input
and the driver will automatically calculate the register values.

This patch fixes the SDB4430 build after commit 6d8962e814c15807dd6ac5757904be2a02d187b8
by explicitly disabling CMD_NFS.
>From the commit message for "Switch from archive libraries to partial linking":
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.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

OMAP4430 SDP 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
