Currently, the tool gives up moving an option quietly if its entry
was not found in Kconfig.
If the option is not defined in the config header in the first
place, it is no problem (as the Kconfig entry may have been hidden
by reasonable "depends on").
However, if the option is defined in the config header, the missing
Kconfig entry is a sign of possible behavior change. It is highly
recommended to manually check if the option has been moved as
expected. In this case, let's add "suspicious" in the log and
change the log color (if --color option is given) to make it stand
out.

56086921 added support for unaligned environments access.
U-boot itself does not support this:
- env_nand.c fails when using an unaligned offset. It produces an
error in nand_erase_opts{drivers/mtd/nand/nand_util.c}
- in env_sf/env_flash the unused space at the end is preserved, but
not in the beginning. block alignment is assumed
- env_sata/env_mmc aligns offset/length to the block size of the
underlying device. data is silently redirected to the beginning of
a block
There is seems no use case for unaligned environment. If there is
some useful data at the beginning of the the block (e.g. end of u-boot)
that would be very unsafe. If the redundant environments are hosted by
the same erase block then that invalidates the idea of double buffering.
It might be that unaligned access was allowed in the past, and that
people with legacy u-boot are trapped. But at the time of 56086921
it wasn't supported and due to reasons above I guess it was never

When signing images, we repeatedly call fit_add_file_data() with
successively increasing size values to include the keys in the DTB.
Unfortunately, if large keys are used (such as 4096 bit RSA keys), this
process fails sometimes, and mkimage needs to be called repeatedly to
integrate the keys into the DTB.
This is because fit_add_file_data actually returns the wrong error
code, and the loop terminates prematurely, instead of trying again with
a larger size value.
This patch corrects the return value and also removes a error message,
which is misleading, since we actually allow the function to fail. A
(hopefully helpful) comment is also added to explain the lack of error
message.
This is probably related to 1152a05 ("tools: Correct error handling in
