Can you share the brand model of the microSD cards that you are using? Just
for reference.

This is what I get:

root@generic:~ # strings /boot/msdos/u-boot.bin | grep "U-Boot 2"
U-Boot 2020.10 (Apr 09 2021 - 03:55:54 +0000)

root@generic:~ # strings /boot/msdos/start4.elf | grep VC_BUILD_ID_
VC_BUILD_ID_USER: dom
VC_BUILD_ID_TIME: 12:10:40
VC_BUILD_ID_VARIANT: start
VC_BUILD_ID_TIME: Feb 25 2021

VC_BUILD_ID_PLATFORM: raspberrypi_linux
VC_BUILD_ID_VERSION: 564e5f9b852b23a330b1764bcf0b2d022a20afd0 (clean)

PS: I've installed netBSD using the same card / pi 3 B+ combination and it
runs ok at 50 MHz. I'll try tomorrow on the pi 4

```
arm64# dmesg | grep sdmmc | grep MHz
[     2.009317] sdmmc1: 4-bit width, 50.000 MHz
```
