The bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

This adds support for the clocktree on zynq7000 SoCs.
The patch is based on clocks.c from the larger patch
ARM: zynq: add suppport for Zynq 7000 SoC
by Josh Cartwright.
The driver in that patch is converted to a platform_driver and code to
enable plls was added.

On some i.MX SoCs the SDRAM controller has chipselect 2 enabled
by reset default. This confuses our SDRAM size detection. We
already have a fix for this in place. This patch adds the fix
for i.MX35 which needs it aswell. Also since we now detect the
SDRAM size in the SoC specific entry functions we have to apply
the fixup there, too.

This patch fix chipidea-imx usb initialization.
"imx_chipidea_port_init" was moved before PORTSC setup in the
commit "USB i.MX chipidea: implement post init support". This
change breaks usb function with ULPI. Patch moves port initialization
back after PORTSC setup, so it works again.

__pr_printk is a define which uses a local variable 'ret'. This
means that whenever someone does a pr_*("ret: %d\n", ret);
ret will be 0.
Fix this by writing this without a local variable.

This allows to boot a sequence of boot entries until one succeeds.
boot sources can be passed in $global.boot.default, which is now treated
as a list. Also a list of boot entries can be specified as arguments
to the boot script. The entries can be:
- a plain filename from /env/boot/
- a full path to an arbitrary file
- a directory containing boot entries
With this this command:
boot net nand-ubi /env/boot.d
would first use the /env/boot/net entry, if this fails the /env/boot/nand-ubi
entry and if this also fails the files from /env/boot.d/ (which could also
be links to boot scripts)
To make the above the default, global.boot.default would be specified as:
global.boot.default="net nand-ubi /env/boot.d"

Since recently we check for the page being written for not being
empty and do not actually write it when it is. This fails for a
freshly created flash bad block table when all blocks are good.
In this case the bbt code will try to write an empty page, but
with the BBT marker in OOB. This page never gets written, so the
BBT code will not find a bad block table during next start up and
writes it again. Fix this by checking if we want to write OOB data,
if we do, then write the page, even if the data is empty.
