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 in 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.

Please split off this part and make the information available to
userspace (pt_addr + pt_size) if found. This would make it easier
to support use the partition table later in initrd instead.

Please clarify what do you mean by "use the partition table later in
initrd instead".
