Subject: [PATCH v1 10/54] ARM: move needed assembly routines into EFI runtime section
Date: Thu, 18 Dec 2025 11:37:30 +0100 [thread overview]
Message-ID: <20251218111242.1527495-11-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20251218111242.1527495-1-a.fatoum@pengutronix.de>
We want the usual string operation to be available normally in the
runtime services code, so mark them appropriately.
To implement the runtime services for rebooting and shutting down the
system, move the smccc trampolines into the EFI runtime section as well.
