Andrey,

I agree removing the old fit generator is the right path but I am very
surprised it was merged when it broke boards that had not moved to
binman yet. There has been a warning to migrate to binman but there
was never a deadline.

I have not followed the discussion about what was wrong with the FIT
generator or what was specifically 'broken' but boards at least built
and booted with it and now they do not build. I do know there was a
time where I needed a patch that dealt with '@' symbols and I'm not
sure if that ever got merged before the FIT generator was simply
removed. Again, I hadn't thought much of it because I had binman
conversion patches in flight not realizing they would get stuck
because of CI.

I don't really know anything about U-Boot CI but I'm also surprised it
doesn't point out the fact that several boards won't currently build.

Again personally I did not pay attention to d9a6f0eed6 ("tree: imx:
remove old fit generator script") because I already had submitted a
series to move my board to binman (other boards still had not done
this however and would be broken without a change). I see that Stefano
applied d9a6f0eed6 ("tree: imx: remove old fit generator script") on
Oct 7 and he must not have realized it broke boards that had not moved
to binman. Several of us have submitted patches to move to binman and
thus also likely did not notice but those patches never got merged
because of this CI issue.

I see Heiko has a v4 of his patch here
https://patchwork.ozlabs.org/project/uboot/list/?series=279595. Can
that get merged?

It looks to me like the following boards would be currently broken as
they all use CONFIG_SPL_FIT_GENERATOR="arch/arm/mach-imx/mkimage_fit_atf.sh":
cgtqmx8_defconfig
imx8mm-icore-mx8mm-ctouch2_defconfig
imx8mm-icore-mx8mm-edimm2.2_defconfig
imx8mm_beacon_defconfig
imx8mm_venice_defconfig
imx8mn_beacon_2g_defconfig
imx8mn_beacon_defconfig
imx8mq_evk_defconfig
imx8mq_phanbell_defconfig
imx8qm_rom7720_a1_4G_defconfig
pico-imx8mq_defconfig

I don't know exactly how the U-Boot release schedule works and when
2021.01 is released but in order to save these boards from being
broken the following would have to occur:
apply Heiko's [PATCH v4] binman: add support for creating dummy files
for external blobs
(https://patchwork.ozlabs.org/project/uboot/list/?series=279595)
apply the conversion to binman series that has been pending because of
the CI breakage for these boards:
- Adam Ford: imx8mm_beacon* boards
- Tim Harvey: imx8mm_venice boards
- Andrey Zhizhikin: imx8mq_evk
- Peng Fan: imx8mq_phanbell and pico-imx8mq

That would still leave the following boards broken as nobody has
submitted binman patches for them. These are both maintained by Oliver
Graute (added to cc):
imx8qm_rom7720_a1_4G_defconfig
cgtqmx8_defconfig

I believe Stefano is not currently available and I'm not sure when he
is back to merge the pending binman conversion series. Additionally
some of these series may need to be rebased (I know I had to do that
twice because of things being moved to Kconfig)

Tim
