I've got three PPC6700's. Two of them have a boot rom of v2.02, the other is v1.00 on it.
Is there any benefit of v2.x over v1.x? So far , I've been able to do everything with my v1.x that I've been able to do with my v2.x (custom roms,etc) , and I haven't found any info comparing the actual bootloaders.
Not that we've discovered (and trying to mess with the bootloader is a bad idea anyway). The only difference I've noticed is for hard resets, the newer BL requires you to press the space bar after pressing Y.
