Subject: [PATCH v2 2/5] rockchip: px30: list possible SPL boot devices
Date: Mon, 17 Oct 2022 12:46:38 +0200 [thread overview]
Message-ID: <20221017-upstream-ringneck-v2-2-0f03912ebac2@theobroma-systems.com> (raw)
In-Reply-To: <20221017-upstream-ringneck-v2-0-0f03912ebac2@theobroma-systems.com>
From: Quentin Schulz <quentin.schulz@theobroma-systems.com>
BOOTROM sets a bit in a CPU register so that the software can know from
where the first stage bootloader was booted. One use case for this is to
specify the default loading medium for U-Boot proper to match the one
used by the BOOTROM to load the SPL (same-as-spl in
u-boot,spl-boot-order).
Let's create the mapping between BOOTROM value and Device Tree node
names for MMC devices.
