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.
