From 121596a98fea008d15b052879239f2d2b0e16f6b Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Fri, 15 Jul 2022 11:38:54 -0500 Subject: [PATCH] arm: k3: config.mk: Read software revision information from file on HS Read the swrv.txt file from the TI Security Development Tools when TI_SECURE_DEVICE is enabled. This allows us to set our software revision in one place and have it used by all the tools that create TI x509 boot certificates.
