This should include the hash so that image_binary_size is really at the
end of the image, and not some 300 bytes earlier.

Check that the image size matches the size we get from u-boot.bin. If it
doesn't, that generally means that some extra sections are being added to
u-boot.bin, meaning that it is not possible to access data appended to
the U-Boot binary. This is used for device tree, so needs to work.
This problem was introduced by commit b02bfc4. By adding a test we can
prevent a reccurence.

Enable the cache for all devices, unless CONFIG_SYS_DCACHE_OFF is defined.
This speeds up the Beaglebone Black boot considerable.

In some cases, an externally-built device tree binary is required to be
attached to U-Boot. An example is when using image signing, since in that
case the .dtb file must include the public keys.
Add a DEV_TREE_BIN option to the Makefile, and update the documentation.
Usage is something like:
make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb

I do not want to expand this argument, but
I am not sure if DTB stands for "device tree binary".
linux/Documentation often refer it as "device tree blob",
while linux/Documentation/devicetree/booting-without-of.txt
says "device tree block".
> Add a DEV_TREE_BIN option to the Makefile, and update the documentation.
Is it possible to rename it without mentioning _BIN or _BLOB ?
For example, DTB_PATH=... or EXT_DTB=...
or some other variable name you like.

The second comma in '(if $(CONFIG_OF_SEPARATE),-dtb,)' is redundant.
This is duplicating the same image as u-boot-dtb.img
Your way is that "u-boot.img" includes DTB in some time and doesn't in the other.
I am not sure which way is better.
But we don't need two rules to generate the equivalent image.
If you go along with this change, I think it's OK with me.
Please consider removing below in that case:
ifeq ($(CONFIG_SPL_FRAMEWORK),y)
ALL-$(CONFIG_OF_SEPARATE) += u-boot-dtb.img
endif
and
u-boot-dtb.img: u-boot-dtb.bin FORCE
$(call if_changed,mkimage)
Best Regards

I think EXT_DTB is quite a nice name so I've made that change.

I took a look this morning but I'm still not quite sure about this. I
will spend some more time to understand it fully.

When writing values into an FDT it is possible that there will be
insufficient space. If the caller gets a useful error then it can
potentially deal with the situation.
Adjust these functions to return -ENOSPC when the FDT is full.

When adding hashes or signatures, the target FDT may be full. Detect this
and automatically try again after making 1KB of space.

The current size of 1MB is not enough use to use DFU. Increase it for
ARMv7 boards, all of which should have 32MB or more SDRAM.
With this change it is possible to do 'dfu mmc 0' on a Beaglebone Black.
