Kosta, do you see any problems with removing this script? As you might have seen, Pali and Marek did some great work on kwboot in the mean time. Is there anything left in mrvl_uart.sh that kwboot can't handle?
Disclaimer: I am not really a Kirkwood developer or at least not yet (;-p).
Recently, we started playing with mainline U-Boot/Linux kernel as part of an effort to port OpenWrt to the MikroTik RB5009UG [1]. It features an Armada 7040 which is a 64-bit Arm SoC while kwboot mentions 32-bit platforms only. Anyway, so far I was able to boot it using the good oldé mrvl_uart.sh script as follows:

Transfer complete
Trying this with kwboot instead I was not successful as of yet. Not sure whether I am just missing something or support for booting 64-bit platforms would yet need to be added.
If I patch it as follows it actually starts transferring but does not really get too far.
