Subject: [PATCH v2 061/113] efi: add efi_is_loader/efi_is_payload helpers
Date: Mon,  4 Mar 2024 19:59:46 +0100	[thread overview]
Message-ID: <20240304190038.3486881-62-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20240304190038.3486881-1-a.fatoum@pengutronix.de>

So far, whether we are running under EFI was a compile-time decision.
This will change with ARM support, where the same barebox binary can
either probe from DT or from EFI. Prepare for this by adding helpers
to determine whether barebox is acting as EFI loader or as payload.
