Subject: [PATCH v2 0/8] Introduce NVIDIA Tegra Partition Tablex
Date: Fri, 6 Mar 2020 05:12:12 +0300 [thread overview]
Message-ID: <20200306021220.22097-1-digetx@gmail.com> (raw)
Some NVIDIA Tegra devices have GPT entry at a wrong location and others may
even not have it at all. So either a custom workaround for GPT parsing or
TegraPT support is needed for those devices if we want to support them in
upstream kernel. The former solution was already rejected [1], let's try
the latter.
[1] https://patchwork.ozlabs.org/patch/1240809/
Big thanks to everyone who helped with figuring out the TegraPT format!
Changelog:
v2: - Addressed v1 review comments from Stephen Warren by using BIT for
locating BCT position in IRAM.
- Added more validations to the TegraPT parser: partition type is
verified, eMMC instance ID is verified.
- TegraPT parser now doesn't touch any devices other than eMMC.
- EKS (encrypted keys) partition is blacklisted now.
- Implemented eMMC boot partitions scanning. These new patches are
added in a result:
mmc: block: Add mmc_bdev_to_part_type() helper
mmc: block: Add mmc_bdev_to_area_type() helper
mmc: block: Add MMC_QUIRK_RESCAN_MAIN_BLKDEV
mmc: block: Enable partition-table scanning for boot partitions
partitions/tegra: Implement eMMC boot partitions scanning
