No you can use the avm bootloader. Uboot is not recommend because some 
details about your Fritz Box ist in the AVM bootloader (macadresse, 
eeprom wireless).

You don't need any extra hardware but you must find out the IP Adress of 
your Bootloader in most cases it is Here are some Infos 
http://www.wehavemorefun.de/fritzbox/ADAM2_Shell. in FritzOS you can 
find your variables in /proc/sys/urloader/enviroment.
I recommend a seriel cable to control the bootloader but you don't need one.
You have 5 seconds to make a ftp connection to your Fritzbox on boot.

Here are a short description
login to your fritzbox with

user: adam2
pass: adam2

now do the following commands:

debug 1

its time to flash your image to the box, use the squashfs image because 
the jffs image will not work ! Don't override your bootloader or the 
tffs partions !!!

put bin/lantiq/openwrt-lantiq-xrx200-FRITZ7360SL mtd1

after a time flash is ready an you can start restart your fritzbox with
