- 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

- Provide alternate implementations of board_init_f()
board_init_r() for OMAP spl.
- Provide linker script
- Initialize global data
- Add serial console support
- Update CONFIG_SYS_TEXT_BASE to allow for SPL's bss and move
it to board config header from config.mk

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.

In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()

As implemented now the timer used to implement __udelay counts
to 0xffffffff and then gets stuck there because the the programmed
reload value is 0xffffffff. This value is not only wrong but
illegal according to the reference manual.
One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command. The sleep will hang
forever.
The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.
Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the OMAP timer driver.
The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

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 OMAP3 cpu directory contains a syslib file with some utilities
that can be shared by all targets using arm cortexa8 processors,
not only OMAP.

Using the reset command on OMAP36XX/37XX and OMAP4 caused a hang. This
patch uses the reset bit appropriate for each CPU architecture.

The OMAP4 x-load code sets gptimer1 clock source to 32Khz. This isn't
acceptable for udelay. This patch changes from gptimer1 to gptimer2,
which uses sys_clk at 38.4 Mhz.
