Subject: [boot-wrapper PATCH 1/5] Remove unused Set/Way cache helpers
Date: Tue, 24 Aug 2021 14:48:56 +0100	[thread overview]
Message-ID: <20210824134900.34849-2-mark.rutland@arm.com> (raw)
In-Reply-To: <20210824134900.34849-1-mark.rutland@arm.com>

We removed the Set/Way cache maintenance in commit:

  864182b26c20a39d ("Remove cache maintenance")

... but forgot to remove the arch helpers which are now unused.

Remove the unused helpers.
