No: See the later note about the RPi4B Revision.

This is an old U-Boot compared to sysutils/u-boot-* .
There may well be good reasons for using it, for all
I know.

sysutils/u-boot-* got 2021.04 on 2021-Apr-06.
sysutils/u-boot-* got 2021.07 on 2021-Jul-07.

sysutils/u-boot-* got a patch to fix MMC ordering
because 2021.07 had changed something the port
depended on for the ordering, if I udnerstand right.
This update was on 2021-Nov-09.

I do not know if any of the more up to date vintages
would be more appropriate or not.

I can not tell which of the following is in use:

sysutils/u-boot-rpi-arm64
vs.
sysutils/u-boot-rpi-rpi4

The 2021-Nov-09 patching changed both to explicitly
have:

U_BOOT_SLAVE_PORTREVISION_2021.07=	1

in addition to the extra patch.

An RPi4B with the new PMIC would jave the 0x... end in 15,
instead of 14. This is a RPi4B Rev 1.4 (the 14). [The d
is the 8 GiByte indication.] A RPi4B with the new PMIC
would be Rev. 1.5 at this point (15).

I've no clue about the above lines --or related material below.
