Subject: [PATCH v6 1/5] firmware: smccc: Add SMCCC TRNG function call IDs
Date: Wed,  6 Jan 2021 10:34:49 +0000	[thread overview]
Message-ID: <20210106103453.152275-2-andre.przywara@arm.com> (raw)
In-Reply-To: <20210106103453.152275-1-andre.przywara@arm.com>

From: Ard Biesheuvel <ardb@kernel.org>

The ARM architected TRNG firmware interface, described in ARM spec
DEN0098, define an ARM SMCCC based interface to a true random number
generator, provided by firmware.

Add the definitions of the SMCCC functions as defined by the spec.
