Hi Jeroen,
My apologies, I didn't test the tools on BSD. The answers are inline.
Best regards,

Hello Guilherme / Simon,
It seems that commit f86ed6a8d52c99bb2d17d3cac1647edca0c4399c,
"tools: moved code common to all image tools to a separated module."
I guess the culprit is commit a93648d197df48fa46dd55f925ff70468bd81c71,
"imagetool: replace image registration function by linker_lists feature".
Because that commit introduced the linker script to imagetools.
Likely, since some patches depend on each other I was unable to revert
a single commit.
Anyway as far as I am concerned there are two separate
build targets, the bare u-boot having an (almost) naked compiler, beside
stdarg and stdbool? without any other host includes or objects (well with
CONFIG_USE_PRIVATE_LIBGCC=y). U-boot provides linker scripts for them,
and we have fine grained control over them and an excuse to throw any
trick at them if it makes things faster / smaller etc. It is still nice
if this
compiles anywhere though..
On the other hand there are "tools" for the host / target userland, which
should build against the host / targets "std*". Those things should be
buildable
on any decent host / target and be straightforward (and _not_ define KERNEL
etc, since it are userland tools). There is no linker for them afaik, so
tweaking
them seems like a bad idea. Hence I am tempted to remove the use of
linker generated lists from tools...
- and really last, how do I test if it works..
There are two scripts to test the image tools, test-imagetools.sh and
test-fit.py. Running those scripts you make sure the linker list is
properly setup, because it is required by the imagetools to find the image
type.
$ make O=sandbox clean
$ make O=sandbox sandbox_config
$ make mrproper
$ make O=sandbox
$ ./test/image/test-imagetools.sh
$ ./test/image/test-fit.py -u sandbox/u-boot
Sandbox used to build on FreeBSD, but it is quite a mess at the moment.
But a I said, I think the best solution for tools is not to use linker
generated
list in the first place for tools.
Regards,
Jeroen
