I've not tried the u-boot way of working in some time.
I do not know its status or what is a good combination
for it. Nor if it is allowing overclocking, including
if it allows some equivalent of over_voltage=6 .

Looks like your way of copying start4.elf and fixup4.dat did
not preserve the original dates.

You also have the alternative of getting files from:

https://github.com/raspberrypi/firmware/tree/1.20200902/boot/

(Currently, 1.20200902 is the most recent tag.) Or from:

https://github.com/raspberrypi/firmware/tree/master/boot/

(likely a testing software version, likely more recent than
the most recently tagged version.)

> In order to get => 2GHz speeds from the pi4, is UFEI a requirement?

Unsure. uefi is what I have been using. I"ll note that the
3072 MiByte limit should be enabled for reliable operation,
despite what some recent materials may say. (I've demonstrated
a failure today with the limit not imposed.) For uefi/ACPI I
use:

# more /usb_efi/config.txt
arm_64bit=1
enable_uart=1
uart_2ndstage=1
enable_gic=1
armstub=RPI_EFI.fd
disable_commandline_tags=1
disable_overscan=1
device_tree_address=0x1f0000
device_tree_end=0x200000
dtoverlay=disable-bt
over_voltage=6
arm_freq=2000

This context runs at 2 GHz all the time, not varying based on
use.

diable-bt.dtbo is not distributed with the uefi software. I got
it separately. It does not seem to update often.

# ls -ldT /usb_efi/OVERLAYS/*
-rwxr-xr-x  1 root  wheel  1073 Jul 14 18:43:14 2020 /usb_efi/OVERLAYS/disable-bt.dtbo
-rwxr-xr-x  1 root  wheel  1819 Sep  1 14:04:10 2020 /usb_efi/OVERLAYS/miniuart-bt.dtbo

The uefi distribution has miniuart-bt.dtbo included.

I will note that back when I was trying u-boot I found various
things had case sensitive file handling and others did not.
The u-boot context tended to be case sensitive in at least some
parts of some file paths.

I ended up capitalizing to minimize/eliminate renaming for
capitalization when switching contexts. OVERLAYS was an example
of such: something required capitals and other things did not
care. (I do not know the current status for such issues overall.)
