Subject: [PATCH 3/9] ARM: k3: do not mount /boot when booting from eMMC
Date: Wed, 05 Feb 2025 10:48:11 +0100	[thread overview]
Message-ID: <20250205-k3-emmc-v1-3-06679246be41@pengutronix.de> (raw)
In-Reply-To: <20250205-k3-emmc-v1-0-06679246be41@pengutronix.de>

When booting from eMMC we load the subsequent stages from eMMC boot
partitions, so we do not need a boot FAT partition on eMMC. We can
use an unpartitioned area in the eMMC user area in this case, so
bail out from mounting /boot when eMMC boot is detected.
