initrd is especiall useful for the Pogo V3. When you boot with both SATA and multiple USB drives plugged in, it is much easier to use rootfs label to identify the boot drive with bootarg root=LABEL=rootfs. Using other mechanism such as UUID or other identifying means are not very flexible (i.e. U-Boot envs need to change every time you change the boot drive).
Currently, I'm having problem with initrd using kref's configuration as a base, and adding back some initrd options. I got stuck at booting the kernel because it can't find the root device with label. OTOH, booting with initrd and a simple bootarg root=/dev/sda1 is never a problem.
