Subject: [PATCH v5 0/5] Support EFI partition on NVIDIA Tegra devices
Date: Wed, 18 Aug 2021 03:55:42 +0300	[thread overview]
Message-ID: <20210818005547.14497-1-digetx@gmail.com> (raw)

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:

v5: - Implemented alternative_gpt_sector() blk/mmc callback that was
      suggested by Christoph Hellwig in a comment to v4.

    - mmc_bdev_to_card() now checks blk fops instead of the major number,
      like it was suggested by Christoph Hellwig in a comment to v4.

    - Emailed Rob Herring, which was asked by Ulf Hansson in a comment
      to v4. Although the of-match change is gone now in v5, the matching
      is transformed into the new SDHCI quirk of the Tegra driver.

v4: - Rebased on top of recent linux-next.

v3: - Removed unnecessary v1 hunk that was left by accident in efi.c of v2.

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.
