I'm unsure how to reply to this. On the one hand I really like to see
this go in, on the other hand this changes the expectation of what
flash.bin is. We had the same discussion for i.MX8MM.
Because historically, flash.bin is SPL+U-Boot.itb, and for i.MX8MM
people have changed the binman config to generate a single bootable
file again: 028abfd9b1576b45cf756b9a0c978cfe17906314
So, I would ask you to adjust the imx8mq-u-boot.dts changes in the same
way as done for i.MX8MM. You should be able to see the differences
by diffing e.g. these files:
diff -u arch/arm/dts/imx8mq-u-boot.dtsi arch/arm/dts/imx8mm-evk-u-boot.dtsi
