We did set these variables, so it is possible to flash boot and root
partitions separately for booting with stock partition table. This
is useful for U-Boot as secondary bootloader. But it's not good for
U-Boot as primary bootloader because the resulting images have boot
and root partitions separated, so users have to create partitions
themselves and this is very confusing.
I'm suggesting to disable it in favor of doing U-Boot as primary
bootloader, this may be harder for users, but it needs to be done
only once, and this way is more fancy and is supported on more
devices than secondary bootloader.
If someone still wants to use this port with U-Boot as secondary
bootloader they can do "pmbootstrap install --split" and
"pmbootstrap export" to get 2 separate partitions to flash.
