The mkits.sh script help message states hash algorithm can be
specified using the -H command-line option, but it does not work
currently due to a bug in the script.
This patch fixes this problem by changing the option from -S to
-H and specify getopts parameter after it

Allow adding multiple device tree overlay blobs to an image and
generate configurations for each of them.
This is useful on boards with modern U-Boot which allow e.g. user-
configurable peripherals ("shields") in that way.
Note that currently, each generated configuration adds exactly one
overlay on top of the base image, ie. adding multiple overlays at the
same time is not yet supported.

U-boot will reject the nodes with @ for the address since
commit:
79af75f777
This in turn will cause the failure to boot with OpenWrt
generated images.
So, to rectify that simply replace @ with -.

Instead of embedding the initrd cpio archive into the kernel, allow
for having an external ramdisk added to the FIT or uImage.
This is useful to overcome kernel size limitations present in many
stock bootloaders, as the ramdisk is then loaded seperately and doesn't
add to the kernel size. Hence we can have larger ramdisks to host ie.
installers with all binaries to flash included (or a web-based
firmware selector).
In terms of performance and total size the differences are neglectible.

Allow for single (external-data) FIT image to hold kernel, dtb and
squashfs. In that way, the bootloader verifies the system integrity
including the rootfs, because what's the point of checking that the
hash of the kernel is correct if it won't boot in case of squashfs
being corrupted? Better allow bootloader to check everything needed
to make it at least up to failsafe mode. As a positive side effect
this change also makes the sysupgrade process on nand potentially
much easier as it is now.
In short: mkimage has a parameter '-E' which allows generating FIT
images with 'external' data rather than embedding the data into the
device-tree blob itself. In this way, the FIT structure itself remains
small and can be parsed easily (rather than having to page around
megabytes of image content). This patch makes use of that and adds
support for adding sub-images of type 'filesystem' which are used to
store the squashfs. Now U-Boot can verify the whole OS and the new
partition parsers added in the Linux kernel can detect the filesystem
sub-images, create partitions for them, and select the active rootfs
volume based on the configuration in FIT (passing configuration via
device tree could be implemented easily at a later stage).
This new FIT partition parser works for NOR flash (on top of mtdblock),
NAND flash (on top of ubiblock) as well as classic block devices
(ie. eMMC, SDcard, SATA, NVME, ...).
It could even be used to mount such FIT images via `losetup -P` on a
user PC if this patch gets included in Linux upstream one day ;)

Some bootloaders are really keen on just one special
fdt in a multi-image fit image. This is a problem, because
currently this is fixed to "fdt@1".
This patch introduces a new device variable:
DEVICE_FDT_NUM that allows to specify the right
fdt number.
If the value is absent "1" will be chosen.

Due to a line break, printf was accidentally called with three
arguments instead of two, causing a different output than before.
Fix it by splitting the printf command into two lines.
