Subject: [PATCH 2/6] of: remove struct property.unique_id for FDT
Date: Thu, 5 Oct 2017 14:44:18 -0500 [thread overview]
Message-ID: <20171005194422.26224-3-robh@kernel.org> (raw)
In-Reply-To: <20171005194422.26224-1-robh@kernel.org>
Only Sparc uses unique_id, so remove it for FDT builds and shrink struct
property a bit making the unflattened DT less of a memory hog.
