I basically took Armbian's image, DD-ed to an SD card, then wiped out the
rootfs and rebuilding it using debootstrap. I forgot if I did `rm -rf *` or
`mkfs.ext4` for this particular one. But IIRC U-boot's ext4 code had been
patched up to correctly support modern (64bit, checksum) ext4.

Maybe reading works for files up to some size? or I/O block size?
I tried a couple files from /usr/lib, and it seems to fail around 2.5 ~ 3 MiB.

With this patch set applied on top, things load correctly, so it must be
something with the FIFO mode code.

I'm still not getting anything from the kernel, but that's likely some other
issue.
