I've tried this series with our U-Boot (2020.07 based) and it doesn't
work for me as using UBOOT_FORMAT_CUSTOM isn't sufficient as it only
copies the binaries selected but doesn't use it as target [1].

So I wonder, which U-Boot version are you using? Is the flash.bin
created automatically when issuing 'make all'?
In my version of U-Boot it requires to use 'make flash.bin' otherwise it
simply doesn't generate flash.bin.

I believe we would still need a new U-Boot target name [2] but I'd like
to understand how it worked for you

Regards,
Gary
