"Trying to boot from MMC1" information]

Then after X seconds WDT is causing board to reset. After N boot attempts
we enter recovery mode.

To enter the special mode, one needs to short cut two pads with e.g. screw
driver.

After power up the SPL will execute u-boot in which proper actions will be
taken.

It is worth noting that we do not alter envs (even the BOOT_FROM variable)
and unconditionally go to recovery.

This patch is necessary for providing basic bootcount checking in the case
of using "falcon" boot mode in that board.

It forces u-boot proper boot, when we exceed the number of errors.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
include/libfdt.h -> include/linux/libfdt.h
include/libfdt_env.h -> include/linux/libfdt_env.h

and replaces include directives:
#include <libfdt.h> -> #include <linux/libfdt.h>
#include <libfdt_env.h> -> #include <linux/libfdt_env.h>
