Subject: [PATCH v1 0/3] Introduce NVIDIA Tegra Partition Table

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.

Big thanks to everyone who helped with figuring out the TegraPT format!
