U-Boot is running as a 64-bit binary on the IBM-970FX (PPC64 CPU arch),
on one of Marvell evaluation boards (Pythagoras family)!!!

Some of the *NEW* components I've added to U-Boot:
/include/asm-ppc64, /include/ppc970, /include/ppc64_asm.tmpl,
/cpu/ppc970, /lib_ppc64

I want to add 64-bit support to some of the *COMMON* files,
starting with cmd_mem.c. The commands are followed with [.b, .w, .l]
represents display option: 8-bit, 16-bit, and 32-bit, accordingly.
Will it be ok to change it to [.b, .s, .w, .l] for 8, 16, 32, and 64?
If it is not acceptable what do you suggest? new cmd_mem64.c? other?

Tzachi Perelstein
