Subject: [PATCH v2 7/8] mmc: block: Enable partition-table scanning for boot partitions
Date: Fri,  6 Mar 2020 05:12:19 +0300	[thread overview]
Message-ID: <20200306021220.22097-8-digetx@gmail.com> (raw)
In-Reply-To: <20200306021220.22097-1-digetx@gmail.com>

Some NVIDIA Tegra devices store partition table on a boot eMMC partition,
and thus, boot partitions need to be scanned. This patch enables scanning
of the boot MMC partitions. Please note that boot partitions will be
scanned-only, i.e. the scanned boot partitions will be kept hidden.
