I don't think there is anything more needed from the Barebox side. At least the same change works for me and gets me a working HDMI display on the EVK board. I don't use the NXP kernel through, but running a 4.20 based kernel with lot of downstream bits ported. This might be a incompatibility of your kernel with the imx8 ATF version shipped with Barebox.

However, that has been over 5 month ago, so it is entirely possible that newer version of various components might have become problematic. It is probably not a problem in your case, but do keep in mind, that i.MX8MQ mask ROM code uses SD2 as a "backup" boot option, so if it doesn't find anything bootable on the selected (via pins or fuses) medium it will revert to that. If that happens, HDMI firmware present on SD card will _not_ be loaded into HDMI IP block. I've been bitten by this when I was working with a board that I forgot was configured to boot from eMMC and was booting from SD card by coincidence.

I am booting from SD card. And the card with complete NXP image(uboot+kernel) loads completely. When I replace uboot with Barebox, HDMI error happens. The point is, before adding signed_hdmi_firmware into Barebox, I got the error during kernel boot regarding no FW loaded. But after that, kernel detects HDMI FW is loaded but cannot communicate with it.

It is all related to the HDMI FW itself. The one that I took from imx-mkimage repository is different from the one, which is used via Yocto to build final image.
