Subject: [PATCH] Platform/ARM/Morello: Correct the private resources in PPTT
Date: Wed, 19 May 2021 19:04:38 +0530	[thread overview]
Message-ID: <20210519133438.28355-1-chandni.cherukuri@arm.com> (raw)

As per ACPI specification, only the head of the list needs to be
listed as a resources by a processore node, as cache node itself
contains a link to the next level of cache.
