   just to be clear, i have no strong opinion on this either way, but
my understanding is that source files with the name of "common/cmd_*.c"
typically define at least one u-boot "command" with the U_BOOT_CMD macro.
as far as i can tell, cmd_disk.c is the only counterexample of that.

   it may be true that that file provides utility routines for other
actual "commmand" files, but so do many others.  for example, cmd_fdt.c
defines the behaviour of the actual "fdt" command, while fdt-related
utility routines are in fdt_support.c or even in libfdt/.

   it's no big deal, i'm just pointing out that cmd_disk.c flies in the
face of a fairly obvious pattern in u-boot filenaming convention.  and
on that note, i will shut up about it. :-)
