Changelog: v7: - Added r-b from Christoph Hellwig. - Added ack from Davidlohr Bueso. - Renamed MMC_CAP2_ALT_GPT_SECTOR to MMC_CAP2_ALT_GPT_TEGRA, like it was suggested by Ulf Hansson and Thierry Reding. - Squashed MMC raw_boot_mult patch into alternative_gpt_sector() since both now belong to MMC core and it's cleaner to have them in a single change. v6: - Added comment for the alternative_gpt_sector() callback, which was asked by Christoph Hellwig. - Changed alternative_gpt_sector() to take disk for the argument instead of blkdev. This was asked by Christoph Hellwig. - Dropped mmc_bdops check as it was suggested by Christoph Hellwig. - Added missing mmc_blk_put() that was spotted by Christoph Hellwig. - Moved GPT calculation into MMC core and added MMC_CAP2_ALT_GPT_SECTOR flag, like it was asked by Ulf Hansson. Me and Thierry have concerns about whether it's better to have Tegra-specific function in a core instead of Tegra driver, but it also works, so I decided to try that variant. 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  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.  https://email@example.com/T/ Dmitry Osipenko (4): block: Add alternative_gpt_sector() operation partitions/efi: Support non-standard GPT location mmc: block: Support alternative_gpt_sector() operation mmc: sdhci-tegra: Enable MMC_CAP2_ALT_GPT_TEGRA block/partitions/efi.c | 12 ++++++++++++ drivers/mmc/core/block.c | 21 ++++++++++++++++++++ drivers/mmc/core/core.c | 35 ++++++++++++++++++++++++++++++++++ drivers/mmc/core/core.h | 2 ++ drivers/mmc/core/mmc.c | 2 ++ drivers/mmc/host/sdhci-tegra.c | 9 +++++++++ include/linux/blkdev.h | 7 +++++++ include/linux/mmc/card.h | 1 + include/linux/mmc/host.h | 1 + 9 files changed, 90 insertions(+) -- 2.32.0
