David Lechner <dlechner@baylibre.com> says: This is a series adding support for reading U-Boot env directly from SCSI devices that do not have a partition table, similar to how we can already do this for MMC devices. The motivation behind this is that MediaTek's BSP is already using the same disk images for both MMC and UFS devices, so we need to be able to read the env from SCSI devices without requiring a partition UUID. The series starts with cleaning up a few oddities we noticed in the existing code. Then some refactoring so that the env code manages calling scsi_scan() so that we don't have to duplicate that for the new code path. Then finally, the last few patches add and document the new functionality. Link: https://lore.kernel.org/r/20260326-env-scsi-hw-part-support-v1-0-55c9dd07a2cb@baylibre.com

Add CONFIG_ENV_SCSI_HW_PARTITION and supporting code to allow loading the environment directly from a SCSI device without a partition table. Some platforms store the environment directly on the SCSI device without a way to look it up by partition UUID. Signed-off-by: David Lechner <dlechner@baylibre.com>
Rename SCSI_ENV_PART_UUID to ENV_SCSI_PART_UUID. All other environment- related config names are of the form ENV_<name>, so this is more consistent. Signed-off-by: David Lechner <dlechner@baylibre.com> Reviewed-by: Sumit Garg <sumit.garg@oss.qualcomm.com>
The SPL_SAVEENV functionality, when working with an MMC device, can only work with SPL_MMC_WRITE enabled. This however only works with SPL_MMC also being enabled. Update the dependencies to show that if we have enabled SPL_ENV_IS_IN_MMC then we select SPL_MMC_WRITE and make SPL_ENV_IS_IN_MMC depends on SPL_MMC. Signed-off-by: Tom Rini <trini@konsulko.com>

Add support for converting single-copy environment to redundant environment. In case CRC checks on both redundant environment copies fail, try one more CRC check on the primary environment copy and treat it as single environment. If that check does pass, rewrite the single-copy environment into redundant environment format, indicate the environment is valid, and import that as usual primary copy of redundant environment. Follow up 'env save' will then store two environment copies and the system will continue to operate as regular redundant environment system. Add test which validates this upgrade path. The test starts with spi.bin which is pre-populated as single-copy environment and then upgrades that environment to dual-copy environment.
