Merge patch series "env: scsi: support SCSI env without partition UUID" 2026-04-08T17:07:19+00:00 Tom Rini trini@konsulko.com 2026-04-08T17:07:19+00:00 f0000b4a57e9edf8ff8454b9056d767466dff57f 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

scsi: move scsi_scan() call out of scsi_get_blk_by_uuid() 2026-04-08T17:07:07+00:00 David Lechner dlechner@baylibre.com 2026-03-26T22:59:26+00:00 b382cd0973521a5197a097d4e190f47aadb79757 Move scsi_scan() call out of scsi_get_blk_by_uuid(). The only caller, env_scsi_get_part(), should be managing this call since it may also want to use different ways to get the partition information in the future.

env: Make more use of the ENV_SAVE_PTR macro 2026-04-07T17:30:41+00:00 Tom Rini trini@konsulko.com 2026-03-23T19:51:05+00:00 8af4e124875932567cea627e04f26cf5cc529e25 With commit 82b2f4135719 ("env_internal.h: add alternative ENV_SAVE_PTR macro") we introduced the ENV_SAVE_PTR macro but as explained in the commit message, left full conversion for a later time. This commit makes more progress on that front by doing the remaining easy conversions to the new macro. Signed-off-by: Tom Rini <trini@konsulko.com> Changes in v2: - Reduce the number of conversions, some didn't work as expected once CMD_SAVEENV was actually disabled. - Finish converting UBI Cc Rasmus Villemoes <rasmus.villemoes@prevas.dk>
