Since I suspect that I am making a mistake in deploying the files, where 
should each of these things go on a memory card?

The uImage file should go in the first (FAT) partition, of course.

The second partition should contain the root filesystem. I found that unlike 
the legacy configuration, which used ext2, the kernel command line only had 
ext4 and ext3 for the rootfstype. So I changed the command line and stuck with 
the ext2 format for now.

The modules are presumably installed to the second partition as normal, this 
typically being done using the modules_install Makefile target with 
INSTALL_MOD_PATH set to the base of the mounted partition. They should end up 
at the following location within INSTALL_MOD_PATH:


The device tree files are typically installed using the dtbs_install Makefile 
target with INSTALL_PATH set to the location of the boot directory. They 
should end up at the following location within INSTALL_PATH:


Normally, this would be the following in the running system:


This is where I wonder if I am doing something wrong because the device-
trees.tbz download has one file with this path:


Where would this be unpacked? Should it be on the first partition? What 
happened to the dtbs/5.12.0-rc2-letux-l400+ part of the path?
