From d9cd3b8b33f3fb591e243f1f7494ee3fa2963933 Mon Sep 17 00:00:00 2001 From: Dhruva Gole Date: Mon, 5 Aug 2024 19:59:35 +0530 Subject: [PATCH] arm: dts: k3-am625-beagleplay: Package TIFS Stub Add support for packaging the TIFS Stub as it's required for basic Low Power Modes like Deep Sleep. The reason it is packaged using binman and not inherently as part of the DM firmware is because for HS devices, customer owns the customer key and only customer has access to it. DM is release by TI, Since TI doesn't have access to the customer key it cannot have a component that is signed by customer key. Hence, it's left as part of binman to be signed and packaged.
