The FSF address has changed; The FSF site says that
address is
Free Software Foundation
51 Franklin Street, Fifth Floor
Boston, MA 02110-1301
USA
(see http://www.fsf.org/about/contact/)
Instead of updating it each time the address changes,
just drop it completely treewide.

To make am33xx_uart0_soft_reset more flexible rename it to
am33xx_uart_soft_reset and pass the UART base to it.

Storing the boot information in the image itself and passing a pointer
around between images is cumbersome and doesn't fit well with multiimage
support where the pointer we pass around is already occupied by the
devicetree.
Do the same as U-Boot does and store the boot information at the bottom
of the SRAM public stack.
To maintain the compatibility between new xloaders and older barebox
binaries we still pass the boot information to the next stage via pointer.

This introduces a single omap_init function which detects the
SoC and does all further SoC initialization. This is done to get
rid of initcalls without proper SoC protection. The same has been
done for i.MX already.

For DDR2 RAMs, regs->zq_config is not used, which causes the
AM33XX_EMIF4_0_REG(SDRAM_CONFIG) register to be left unconfigured, resulting
in boot failure.
It seems that the DDR2 case was missed during the consolidation in commit
9f122f8bf0. The actual call for the Bone was
removed in 88659d9c4a.

The function am33xx_get_cpu_rev may be called before barebox_arm_entry(),
so we need to avoid switch statements. One example is the BeagleBone,
where we use this function to differenciate between the white and black
variants.

There is a lot of duplicate lowlevel code between the
am33xx boards. Move this code to am33xx_generic and
create structs for sdram settings.

The ROM loader passes the address of a buffer to the MLO in
register 0. Store this data so we can find the boot source later.
On the same way the bootinformation are passed to the barebox,
then. It has to be enshured that r0 contains always the
buffer or the boot source detection will not work.
Applied this on all OMAPs. This patch is based on work of
Jan Luebbe <jlu@pengutronix.de>.
Compile tested on all OMAP boards.
Tested on pcm049, phyCARD-A-L1 and pcm051.

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.
Also clean up includes in board files.

This adds a function to register the cpws device and another one
to register the MAC addresses provided by the am33xx.
