This patch provides support in u-boot for renaming GPT partitions. The renaming is accomplished via new 'gpt swap' and 'gpt rename' commands.
The 'swap' mode returns an error if no matching partition names are found, or if the number of partitions with one name does not equal the number with the second name. The 'rename' variant always succeeds as long as a partition with the provided number exists.
Rewriting the partition table has the side-effect that all partitions end up with "msftdata" flag set. The reason is that partition type PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte() function. This does not appear to cause any harm.
Changes since v7:
-- Removed several casts in create_gpt_partitions_list() and do_rename_gpt_parts() as suggested by Lothar Waßmann. The cast of gpt_part_info.name to char* is needed to silence a compiler warning.
-- Substituted simple_strtol() for atoi() in do_gpt_rename_parts() as suggested by Tom Rini and Wolfgang Denk.
-- Fixed bug in do_rename_gpt_parts() where 0 was returned as a valid number of partitions with which to continue.
-- Added a comment to do_rename_gpt_parts() noting that the debug() string it optionally prints is useful as input to the pre-existing 'gpt write' and 'gpt verify' commands.
-- Changed some -1 return values to -ENODEV and -EINVAL as suggested by Tom Rini.
Can you please remove the changelog from the commit message, instead put it in the commit-notes section below ---?
