I know this was copied from SolidRun but I'm not a fan of the IMX_FIT
name. True flash.bin includes a FIT image but SPL/FW etc are outside of
it, it's not just a FIT image.
Maybe NXP will do another boot image format in the future that will also
include a FIT image but the rest would be different.
Since the U-Boot target is simply "flash.bin" I would name it

You can't do that unfortunately, you need to either have a test around
that option or add a depends on BR2_PACKAGE_FREESCALE_IMX.
Otherwise it will give this:
WARNING: unmet direct dependencies detected for BR2_PACKAGE_FIRMWARE_IMX
Depends on [n]: BR2_PACKAGE_FREESCALE_IMX [=n] && (BR2_arm [=y] || BR2_aarch64 [=n])
Selected by [y]:
- BR2_TARGET_UBOOT_FORMAT_IMX_FIT [=y] && BR2_TARGET_UBOOT [=y]
