The default for the C portion of the u-boot compile is set to dwarf-2 because the -g option for gcc 3.x defaults to dwarf-2, but the assembly portion is not.
If possible, I would like to see the debug formats made consistent so as to allow the debugger to more reliably step through assembly source with gdb and other debuggers with the more modern dwarf2 debug format. I have tested this change with gcc 3.4.3 on Arm9, MPC82xx, PPC85xx, PPC 40x and PPC 44x. I also tested with ELDK 3.1.1 on all the PPC archs and it works quite well.
