[These notes are based on a normal sdcard, not my historical
e.MCC on an adapter. The e.MMC context no longer directly
boots.]

I've been running head -r337400 with then-modern:

A) /boot/efi/dtb/
   (/boot/efi being a mount of the msdosfs,
    dtb/ being copy of target media's UFS /boot/dtb/ )
B) /boot/efi/EFI/BOOT/bootaa64.efi
   (copy of . . ./stand/efi/loader/loader.efi from the build tree)
and with -r476715 /usr/port 's:
C) sysutils/u-boot-pine64
  (via /usr/local/share/u-boot/u-boot-pine64/u-boot-sunxi-with-spl.bin dd'd)

My boot sdcard has a full installworld installkernel but I normally have
its /etc/fstab edited to redirect the root file system (and swap partition)
to a USB drive.

But I've had no operational troubles so far when booted to the sdcard (via
an edit if its /etc.fstab file to self-reference the root file system).

For reference:

The kernel is from:

# more /usr/src/sys/arm64/conf/GENERIC-NODBG 
#
# GENERIC -- Custom configuration for the arm64/aarch64
#

include "GENERIC"

ident   GENERIC-NODBG

options         ALT_BREAK_TO_DEBUGGER

# For minimum debugger support (stable branch) use:
#options        KDB_TRACE               # Print a stack trace for a panic
options         DDB                     # Enable the kernel debugger

nooptions       MALLOC_DEBUG_MAXZONES   # Separate malloc(9) zones
nooptions       BUF_TRACKING
nooptions       FULL_BUF_TRACKING



Notes:

I do get the two messages during boot:

mmc0: ACMD42 failed, RESULT: 4
mmc0: Card at relative address 43690 failed to set bus width

but things seem to be operating fine.

Because of my use of WITHOUT_BINTUTILS for buildworld buildkernel
I added:

BUILD_DEPENDS+=	objdump:devel/binutils

to:

/usr/ports/sysutils/u-boot-master/Makefile

in order for sysutils/u-boot-pine64 to build under
poudriere-devel .
