Subject: [PATCH v3 09/10] mmc: sdhci-tegra: Enable boot partitions scanning on Tegra20 and Tegra30
Date: Mon, 23 Mar 2020 19:34:30 +0300 [thread overview]
Message-ID: <20200323163431.7678-10-digetx@gmail.com> (raw)
In-Reply-To: <20200323163431.7678-1-digetx@gmail.com>
Consumer-grade devices usually have a custom NVIDIA Tegra Partition table
used by built-in eMMC storage. On some devices partition table resides on
a boot eMMC partition, and thus, the boot partitions need to be scanned.
