2023-11-10bootstd: Skip over bad device during bootflows scanningTony Dinh1-1/+1
During bootstd scanning for bootdevs, if bootdev_hunt_drv() encounters a device not found error (e.g. ENOENT), let it return a successful status so that bootstd will continue scanning the next devices, not stopping prematurely. Background: During scanning for bootflows, it's possible for bootstd to encounter a faulty device controller. Also when the same u-boot is used for another variant of the same board, some device controller such as SATA might not exist. I've found this issue while converting the Marvell Sheevaplug board to use bootstd. This board has 2 variants, the original Sheevaplug has MMC and USB only, but the later variant comes with USB, MMC, and eSATA ports. We have been using the same u-boot (starting with CONFIG_IDE and later with DM CONFIG_SATA) for both variants. This worked well with the old envs-scripting booting scheme.

2023-11-07scsi: Forceably finish migration to DM_SCSITom Rini5-276/+6
The migration deadline for moving to DM_SCSI was v2023.04. A further reminder was sent out in August 2023 to the remaining platforms that had not migrated already, and that a few more over the line (or configs deleted). With this commit we: - Rename CONFIG_DM_SCSI to CONFIG_SCSI. - Remove all of the non-DM SCSI code. This includes removing other legacy symbols and code and removes some legacy non-DM AHCI code. - Some platforms that had previously been DM_SCSI=y && SCSI=n are now fully migrated to DM_SCSI as a few corner cases in the code assumed DM_SCSI=y meant SCSI=y.

2023-10-22sunxi: remove CONFIG_SATAPWRAndre Przywara1-0/+9
The CONFIG_SATAPWR Kconfig symbol was used to point to a GPIO that enables the power for a SATA harddisk. In the DT this is described with the target-supply property in the AHCI DT node, pointing to a (GPIO controlled) regulator. Since we need SATA only in U-Boot proper, and use a DM driver for AHCI there, we should use the DT instead of hardcoding this. Add code to the sunxi AHCI driver to check the DT for that regulator and enable it, at probe time. Then drop the current code from board.c, which was doing that job before. This allows us to remove the SATAPWR Kconfig definition and the respective values from the defconfigs. We also select the generic fixed regulator driver, which handles those GPIO controlled regulators. Please note that the OrangePi Plus is a bit special here, it's a H3 board without native SATA, but with a USB-to-SATA bridge. The DT models the SATA power via a VBUS supply regulator, which we don't parse yet in the USB PHY driver. Use the hardcoded CONFIG_USB3_VBUS_PIN for that board meanwhile.

During cold start, with some HDDs, mv_sata_identify() does not populate the ID words on the 1st ATA ID command. In fact, the first ATA ID command will only power up the drive, and then the ATA ID command processing is lost in the process. Tests with: - Seagate ST9250320AS 250GB HDD and Seagate ST4000DM004-2CV104 4TB HDD. - Zyxel NSA310S (Kirkwood 88F6702), Marvell Dreamplug (Kirkwood 88F6281), Seagate GoFlex Home (Kirkwood 88F6281), Pogoplug V4 (Kirkwood 88F6192). Observation: - The Seagate ST9250320AS 250GB took about 3 seconds to spin up. - The Seagate ST4000DM004-2CV104 4TB took about 8 seconds to spin up. - mv_sata_identify() did not populate the ID words after the call to mv_ata_exec_ata_cmd_nondma(). - Attempt to insert a long delay of 30 seconds, ie. mdelay(30_000), after the call to ata_wait_register() inside mv_ata_exec_ata_cmd_nondma() did not help with the 4TB drive. The ID words were still empty after that 30s delay. Patch Description: - Added a second ATA ID command in mv_sata_identify(), which will be executed if the 1st ATA ID command did not return with valid ID words. - Use the HDD drive capacity in the ID words as a successful indicator of ATA ID command. - In the scenario where a box is rebooted, the 1st ATA ID command is always successful, so there is no extra time wasted. - In the scenario where a box is cold started, the 1st ATA command is the power up command. The 2nd ATA ID command alleviates the uncertainty of how long we have to wait for the ID words to be populated by the SATA controller.
