boot dsp in lcdk

From the document, http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L138#Booting_DSP_Binaries

i find
"This section provides information on how to boot a DSP executable on ARM-boot devices. An ARM user boot loader (UBL) will run first and is required to wake up the DSP, which will begin execution of the DSP application. The ARM and DSP programs are combined into a single AIS image which can be flashed and booted directly."

(1) Do ti provide arm ubl project for lcdk?

(2) arm ubl and arm bootloader(starterware),is the same?
    if yes,how to use the bootloader project in starterware?

(3) if ti does not provide the arm ubl for lcdk, i want to modify the evm demo(include ubl). What do I need to be careful of?

thanks.
