[U-Boot-Users] [PATCH] - request to change default debug assembly flags from stabs to dwarf2

[Wessel, Jason]

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.
