Use the Banana Pi M2 Berry U-Boot defconfig.
U-Boot v2026.07 provides bananapi_m2_berry_defconfig. The Ultra defconfig selects the Ultra device tree and enables CONFIG_MMC_SUNXI_SLOT_EXTRA=2.

Description
BananaPi M2 Berry shares much of the M2 Ultra which is already supported. But for HDMI output, it needs a different device tree in armbianEnv.txt.
How Has This Been Tested?
Added entry manually to /boot/armbianEnv.txt and successfully verified the correct output to the HDMI port.
