mention the more common algorithm.

Cover-letter:
luks: Provide support for LUKSv2
Modern systems mostly use LUKSv2 as it is more secure that v1. This
series provides an implementation of this feature, making use of the
existing 'luks unlock' command.
One interesting part of this series is a converter from JSON to FDT, so
that U-Boot's existing ofnode interface can be used to access the
hierarchical data in JSON text. This obviously results in quite a bit
of new code, but it is more robust than trying to parse the text
directly using strstr(), etc. The choice of JSON for LUKS was presumably
made with larger code bases in mind, rather than a firmware
implementation.
