Subject: [PATCH] arm64: dts: ti: k3-j7200: Fix the L2 cache sets
Date: Fri, 12 Nov 2021 22:36:38 -0600 [thread overview]
Message-ID: <20211113043638.4358-1-nm@ti.com> (raw)
A72's L2 cache[1] on J7200[2] is 1MB. A53's L2 is fixed line length of
64 bytes and 16-way set-associative cache structure.
1MB of L2 / 64 (line length) = 16384 ways
16384 ways / 16 = 1024 sets
Fix the l2 cache-sets.
