The bootsource functions are not specific to the first stage
bootloader. They may also be used for detecting the
bootsource to decide where to load the environment from.

All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.

On some SoCs (for example AM35xx), the ROM bootloader passes useful
information in r0 when jumping to barebox.
To avoid overwriting this in the generic reset code, we introduce
common_reset as a C function and as an assembler macro. This is then
called form the reset entry point (either in common or in board code).
This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

TPS62361 is the new power supply used in OMAP4460 that
supplies vdd_mpu.
VCORE1 from Phoenix supplies vdd_core and VCORE2 supplies
vdd_iva. VCORE3 is not used in OMAP4460.

Instead of passing several options into the nand register function
it is much more straight forward to just pass the platformdata.
While at it, rename the function to omap_add_gpmc_nand_device to
better describe what it does.

Currently, there are multiple definitions of run_shell()
for each board that can be build in "xload" configuration.
Now there is only one function used by all boards.
The functions defined in xload.c are used only when "xload"
configuration used; but it gets compiled unconditionally.
This has been fixed as well.

Commit c71a77ab8 (ns16550: switch to resource) has introduced generic
read/write access to 16550 register and a 'shift' parameter to allign
register index to physicall registers.
The correct 'shift' value was missing in all omap based boards.
Corrected this to 2 which has fixed the problem.
Tested on a PCM-049 phyCORE-OMAP4 board.

The new MMU setup will need SDRAM base addresses and sizes.
For this reason convert the MMU enabled ARM boards:
- move mem setup to mem_initcall. This is early but
still makes sure that we already have the console available
- move MMU setup in this initcall temporary as after the mmu_init will generic
