All NVIDIA Tegra devices use a special partition table format for the internal storage partitioning. Most of Tegra devices have GPT partition in addition to TegraPT, but some older Android consumer-grade devices do not or GPT is placed in a wrong sector, and thus, the TegraPT is needed in order to support these devices properly by the upstream kernel. This patch adds support for NVIDIA Tegra Partition Table format that is used at least by all NVIDIA Tegra20 and Tegra30 devices.
