From fa25c1ddd35738c6894a7deba832c1bb8e6a7f57 Mon Sep 17 00:00:00 2001 From: Dhruva Gole Date: Mon, 5 Aug 2024 19:59:34 +0530 Subject: [PATCH] doc: ti: am62*: Mention TIFS Stub in img fmts and boot flow Since AM62x, AM62P and AM62A all use similar boot flows and their low power mode s/w ARCH is also similar in the way that they make use of the TIFS Stub, update their documentation to show where TIFS Stub is.
