Yocto imx-boot recipe

[AlekseyM]

I try to create my machine for imx8mm. I configured everything and tested it in a standalone variant, and everything worked. 
For now, I try to configure Yocto for that.
Below is the log after the command 

bitbake core-image-minimal

I configured something incorrectly because instead of ddr4_dmc I should have flash_ddr4_dmc. (I added this target to soc.mak with the patch)

Do you know where target configuring is?

I find it.
in file {MACHINE}.conf

config IMXBOOT_TARGETS set the name that should be equal to one of the targets in imx-boot.
