Here we seem to hit an issue with the CI. blobs (lpddr*) are required
for the imx8mm boards. Binman reports the missing files only as a
warning and buildman does not care about that:
----
+WARNING 'mkimage.flash.mkimage' not found, resulting binary is not-functional
----

With the imx8mq boards switching to binman we also need an additional
fw part (signed_hdmi_imx8m.bin). But other than the lpddr firmware as
blob the signed_hmdi'_imx8m.bin is passed to mkimage and mkimage exits
with an error. Thats leads to the error:
----
binman: Error 1 running 'mkimage -d ./mkimage.spl.mkimage -n
spl/u-boot-spl.cfgout -T imx8mimage -e 0x7e1000
./mkimage-out.spl.mkimage': signed_hdmi_imx8m.bin: Can't open: No such
file or directory
----

Currently I do not have an idea how to handle that. Anyone else?
