[PATCH 0/2] improve 'read' command, add 'write' command

[Rasmus Villemoes]

The first patch simplies do_read somewhat by making use of an existing
helper instead of parsing the dev_part string manually. As a bonus
(and my actual motivation), it now understands dev#partname syntax -
hard-coded partition numbers are so last decade.

I also need the symmetrical operation, being able to write to a named
raw partition, and fortunately it doesn't require that many lines of
code to implement that.

There's a very minor change in the error reporting due to using
cmdtp->name to generate the new messages, but I don't think "Error
reading blocks" offers much that "read error" doesn't.



Rasmus Villemoes (2):
  cmd: read: use part_get_info_by_dev_and_name_or_num() instead of
    open-coded dev_part parsing
  cmd: introduce 'write' command
