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: v3: - Fixed "BUG: KASAN: slab-out-of-bounds in tegra_partition". Thanks to Peter Geis for noticing the problem. - The MMC boot partitions scanning is now opt-in. See this patch: mmc: block: Support partition-table scanning on boot partitions - The found MMC boot partitions won't be assigned to the MMC boot block device ever due to the new GENHD_FL_PART_SCAN_ONCE flag. This makes us to ensure that the old behavior of the MMC core is preserved for a non-Tegra MMC-block users. New patches in v3: block: Introduce GENHD_FL_PART_SCAN_ONCE mmc: sdhci-tegra: Enable boot partitions scanning on Tegra20 and Tegra30
I forgot to mention that the TegraPT Kconfig entry now depends on MMC, which was suggested by Randy Dunlap in the review comment to the v2.
