The core support was brought by Marc and Sascha.
The cache choice was fixed by Luotao Fu.
Some gpio and devices addons were provided by Robert.

Barebox cannot boot the recent mainline Linux kernels for the
i.MX21ADS board anymore when using TFTP, because the heap is too
small.
This is solved by increasing the heapsize to 5Mbyte.

- use KERN_ERR for messages when NAND-ID detection fails
- report the IDs also if not found
- print the errno if nand_scan failed

This simplifies the code somewhat. The user visible change here is
that we now ignore the compression specified in the uImage. Instead
we detect the compression type from the data which also means that
we now support lzo compressed uImages.

Using the new uncompress function we can now implement a command which
can uncompress all known compression types. This supplements the unlzo
command.

uncompress() has the same prototype as the various kernel decompress
functions. It automatically detects the compression type and selects
the correct uncompress function.

Several filetypes can be autodetected. Barebox could make use
of this in several ways:
- Add a command to detect filetypes
- detect arm zImages and uImages to unify the different boot commands
- maybe detect UBI or JFFS2 images to construct parts of the kernel
command line
- select correct uncompression function based on filetype
This patch adds basic support to detect filetypes.

Instead, let the user select them manually so that bootm supports
all compression types compiled in.

Allow the user to manually select the uncompression support
he wants to have so that we have a single point where a user
can see which uncompression support will be compiled in.

The kernel uncompression functions have a unified API. Switch
to the kernel implementation to unify the different uncompression
APIs. As a bonus the kernel implementation is much smaller.

All handlers used to just relocate the image without any checks, so
we are doomed if we write outside of SDRAM or will overwrite ourselves.
Move the relocation up to the generic part where we have a chance
of catching these issues.

the uImage should be relocated to load_address. This is handled correctly
in gzip/bzip2 compressed images, but not in uncompressed images. fix this.
Also, when a variable is not used once without casting to another type it
probably means that its type is wrong.

Now that the arch_number and system_rev variables can be set from
the environment we don't need the old bootm command line switch
mechanism anymore.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
arch_number is currently exported to the environment but not read back
on boot time which is rather confusing. system_rev and system_serial
are not exported to the environment but can be set in board specific
code.
This patch exports all these variables to the environment and reads them
back on boot time. All variables get a armlinux_ prefix, so the
arch_number environment variable gets renamed.

We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.
