This might not be related, but looking at the ATF branch [imx_5.4.3_2.0.0] - it appears to be too old, at least for i.MX8M Plus. I was able to run the U-Boot 2020.10 with ATF built from [imx_5.4.47_2.2.0] on the i.MX8M Plus and it does boot successful.

Boot log show the following banner when BOOTROM finishes up the copy:
NOTICE:  BL31: v2.2(release):rel_imx_5.4.47_2.2.0-0-gc949a888e-dirty
NOTICE:  BL31: Built : 05:51:50, Sep  9 2020

Peter,
i.MX8M Plus support in NXP ATF fork appears to be added by commit https://source.codeaurora.org/external/imx/imx-atf/commit/?id=6b8249ff58cc8853396498a074535dcd7f81beaf, and that came in ATF revision far newer than indicated in doc/board/freescale/imx8mp_evk.rst

Try to rebase your ATF to [c949a888e909811db191500c51456391dff61284] and build according to the board doc file.
