Subject: [PATCH] bootm: fit: add option to add DT snipped that contains fit public key
Date: Fri, 9 Feb 2018 11:01:24 +0100 [thread overview]
Message-ID: <20180209100124.4119-1-s.hauer@pengutronix.de> (raw)
From: Marc Kleine-Budde <mkl@pengutronix.de>
This makes it easier for build systems to include a configurable dts
snippet which holds the public keys for FIT images.
Usage:
Add to your dts:
#ifdef CONFIG_BOOTM_FITIMAGE_PUBKEY
#include CONFIG_BOOTM_FITIMAGE_PUBKEY
#endif
