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!
