This patch adds support for LZ4 decompression in the Linux Kernel.
LZ4 Decompression APIs for kernel are based on LZ4 implementation
by Yann Collet.

cdev_open() opens a cdev by name. This introduces cdev_do_open which
allows to open a cdev when the cdev is already found by other means.

currently most partition cdevs have the name <devname>.<partname>
This makes it hard to find a partition by <partname>. This introduces
a partname field in struct cdev so that.

When changing the rates of the ssp clocks we have to poll the
busy bit, but only when they are enabled. The current code can
not check this properly since the gates are registered as children
of the dividers. This has the effect that when the gate is disabled
the busy bit will be set forever resulting in a freezed system.
Fix this by making the gates parents of the dividers which allows
clk_is_enabled to return the correct result.
The Kernel has the same problem, but here the busy polling is
limited to 10ms, so probably noone noticed this.
The datasheet mentions that the ssp dividers shall only be changed
when the clocks are enabled. The kernel and barebox currently ignore
this. I don't know what effect violating this rule has.

In some cases, the address of the devicetree, which is obtained
dynamically, may be located in the kernel text area, which leads
to overwrite devicetree by kernel. The patch uses the address for
devicetree, provided by board, if it possible.

The ifdefs around the SoC specific boot_nand_external functions
can be removed when all functions go into their own sections so
that the linker can discard the unused functions.
This also adds a #ifdef BROKEN around the i.MX21 code which currently
does not have the imx21_barebox_entry function.

Instead of ifdeffing out the correct NFC base address just pass
it to imx_nand_load_image which is called from SoC specific
context anyway.

Add support for the GK802 'QUAD CORE Mini PC', which seems to be loosely

It is supposedly identical to the Hiapad Hi802.

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.

of generating them as *.S generate them as *.dcd.S to better identify them
as generated files. These are then added to .gitignore.

The old way to boot tiny210 was to restart barebox after loading stage2 image.
This turned out to be unstable and stopped working after barebox refactoring.
Now jump to the same position in the loaded code instead of starting it from
the very beginning.

This reverts commit 08c0e206b3.
The external NAND boot code currently uses the _text linker variable
to determine a place for the image. This doesn't work with multi image
support which will link the binary at 0x0. Revert multi image support
for the pcm038 for now until a solution is found.
