md5sum arguments

[Antony Pavlov]

Hi All!

Current 'md5sum' command gets FILE|AREA argument, e.g.


  barebox:/ help md5sum 

  md5sum - calculate MD5 checksum

  Usage: md5sum FILE|AREA...

  Calculate a MD5 digest over a FILE or a memory area.

The *nix 'md5sum' gets [FILE]... argument.
This behavour can be misleading. E.g. today I have tryed this command sequence on
my qemu-malta machine:

  barebox:/ memcpy -s /dev/zero -d 1M 0 0 0x100000
  barebox:/ md5sum 1M

md5sum just hangs!


But this command sequence works fine:

  barebox:/ memcpy -s /dev/zero -d zeros 0 0 0x100000
  barebox:/ md5sum zeros                             
  b6d81b360a5672d80c27430f39153e2c  zeros 0x00000000 ... 0xffffffffffffffff


Do we really need this?

We can use 'addpart' on /dev/memory for creating partial memory device and run md5sum on it.
