[PATCH] cmd: usb: Prevent reset in usb tree/info command
by Xavier Drudis Ferran 19 Jun '23

19 Jun '23

When DISTRO_DEFAULTS is not set, the default environment has bootcmd=bootflow and this will cause a UCLASS_BOOTDEV device to be added as sibling of those UCLASS_BLK devices in boot_targets, until boot succeeds from some device. If none succeeds, and usb is in boot_targets, and an usb storage device is plugged to some usb port at boot time, its UCLASS_MASS_STORAGE device will have a UCLASS_BOOTDEV device as child, besides a UCLASS_BLK child. If once the boot fails the user enters at the U-Boot shell prompt: usb info or usb tree The code in cmd/usb.c will eventually recurse into the UCLASS_BOOTDEV and pass a null pointer to usb_device (because it has no parent_priv_). This causes a reset. Fix it (twice) by checking for null parent_priv_ and adding UCLASS_BOOTDEV to the list of ignored class ids before the recursive call. This prevents the current particular problem with UCLASS_BOOTDEV, even in case it ever gets some parent_priv_ struct which is not an usb_device, despite being the child of a usb_device->dev. And it also prevents possible future problems if other children are added to usb devices that don't have parent_priv_ because they are not part of the usb tree, just abstractions of functionality (like UCLASS_BLK and UCLASS_BOOTDEV are now).

[PATCH 1/2 v2] efi_loader: use efi_install_multiple_protocol_interfaces()
by Ilias Apalodimas 19 Jun '23

19 Jun '23

The TCG2 protocol currently adds and removes protocols with efi_(add/remove)_protocol(). Removing protocols with efi_remove_protocol() might prove problematic since it doesn't call DisconnectController() when uninstalling the protocol and does not comply with the UEFI specification. It's also beneficial for readability to have protocol installations and removals in pairs -- IOW when efi_install_multiple_protocol_interfaces() is called, efi_uninstall_multiple_protocol_interfaces() should be used to remove it. So let's swap the efi_add_protocol() as well.

[PATCH v2 0/7] phy: sun4i: Allwinner F1C100s/H616 support and cleanup
by Andre Przywara 19 Jun '23

19 Jun '23

Hi, version 2 of this series does not change anything in the first three patches adding F1C100s support (apart from adding Jernej's review tags, many thanks for that!), but also adds support for the H616 USB PHY. This is a bit more involved this time, since the USB PHY on this SoC requires some weird quirk to enable most ports. Along with this it adds some cleanup that we used in the Linux driver, which helps to keep the code clean and simplifies future support. Patch 1/7 fixes a bug that prevented the V3s from being supported, and also affects the F1C100s. Patch 2/7 adds the compatible string for the F1C100s, along with its specific properties. Patch 3/7 uses the opportunity to cleanup the U-Boot Kconfig selection of the sunxi USB PHY, and patch 4/7 continues the spring clean with copying some PHY quirk rework done in the Linux kernel recently. The remaining three patches then deal with the H616 USB PHY: patch 5 adds the quirk support, patch 6 wires up the compatible string, while the final patch enables USB support in the defconfig of the two supported boards. Please have a look and test!
