From c71f213fa5afae40cc7e5365585f5cdc51b135df Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Wed, 18 Dec 2019 21:23:02 +0300 Subject: soc/tegra: fuse: Warn if straps are not ready Now both Chip ID and HW straps are becoming available at the same time, thus we could simply check the availability of the ID in order to check the availability of the straps. We couldn't check straps for 0x0 because it could be a correct value. This change didn't uncover any problems, but anyways it is nicer to have straps verified for consistency with the Chip ID verification.
