[PATCH v2 0/3] Support EFI partition on NVIDIA Tegra devices

[Dmitry Osipenko <digetx@gmail.com>]

This series adds the most minimal EFI partition support for NVIDIA Tegra
consumer devices, like Android tablets and game consoles, making theirs
EMMC accessible out-of-the-box using downstream bootloader and mainline
Linux kernel.  EMMC now works on Acer A500 tablet and Ouya game console
that are already well supported in mainline and internal storage is the
only biggest thing left to support.

Changelog:

v2: - This is continuation of [1] where Davidlohr Bueso suggested that it
      should be better to avoid supporting in mainline the custom gpt_sector
      kernel cmdline parameter that downstream Android kernels use.  We can
      do this for the devices that are already mainlined, so I dropped the
      cmdline from the v2 and left only the variant with a fixed GPT address.
