ROM Bootloader

I was trying to understand the bootup sequence for the omap used on 
Logic's OMAP L138 Experimenter Kit. 

Can someone please help me understand how the boot up happens, as 
we need a non-volatile memory at the reset vector location(L138 have RAM at addreess 0xFFFF0000). So how does the control reach the ROM 
boot loader(RBL). Do we have some kind of remap of memory map 
happenning here.

Thanks in Advance

    For this device, the DSP will come up first executing from a from a non-volatile memory location. It will then have the ARM reset vectors copied to the ARM RAM and take the ARM out of reset. No memory map remapping occurs.
