Subject: [PATCH 2/3] crypto/fsl: Introduce SPL_FSL_CAAM_RNG
Date: Fri, 26 Apr 2024 01:02:08 +0200 [thread overview]
Message-ID: <20240425230314.497203-2-marex@denx.de> (raw)
In-Reply-To: <20240425230314.497203-1-marex@denx.de>
Add SPL variant of SPL_FSL_CAAM_RNG so that the SPL_FSL_CAAM_RNG can
be disabled in SPL if necessary. This may be necessary due to e.g.
size constraints of the SPL.
