actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow
so now rename it as int timer_init(void) and use interrupt_init for interrupt
btw also remane the corresponding file to the functionnality implemented
as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c

This patch moves the malloc initialization before calling flash_init().
Upcoming changes to the NOR FLASH common CFI driver with optional
MTD infrastructure and MTD concatenation support will call malloc().
And nothing really speaks against enabling malloc just a little earlier
in the boot stage. Some architectures already enable malloc before
calling flash_init() so they don't need any changes here.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
Also rename load_sernum_ethaddr() to misc_init_r() so we don't need to
handle this board specially in common ARM code.

This patch corrects a small bug in the "if" condition:

Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.
This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.
Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

DM644x is just one of a series of DaVinci chips that use the EMAC driver.
By replacing all the function names that start with dm644x_* to davinci_*
we make these function more portable. I have tested this change on my EVM.
DM6467 is another DaVinci SOC which uses the EMAC driver and i will
be sending patches that add DaVinci DM6467 support to the list soon.

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.
Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions. flag isn't currently used but might be in the future so
we left it alone.

If CONFIG_SKIP_RELOCATE_UBOOT is set the flag GD_FLG_RELOC is usually
never set, because relocation to RAM is actually never done by U-boot
itself. However, several pieces of code check if this flag is set at
some time.
So, to make sure this flag is set on boards skipping relocation, this
is added to the initialisation of U-boot at a moment where it is safe
to do so.

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.
When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.
