usb: Add environment based device ignorelist

2024-04-12T12:53:13Z

Add the environment variable "usb_ignorelist" to prevent USB devices listed in it from being bound to drivers. This allows to ignore devices which are undesirable or trigger bugs in u-boot's USB stack. Devices emulating keyboards are one example of undesirable devices as u-boot currently supports only a single USB keyboard device. Most commonly, people run into this with Yubikeys, so let's ignore those in the default environment. Based on previous USB keyboard specific patches for the same purpose.

boot: add support for button commands

2024-02-13T20:38:49Z

With the relatively new button API in U-Boot, it's now much easier to model the common usecase of mapping arbitrary actions to different buttons during boot - for example entering fastboot mode, setting some additional kernel cmdline arguments, or booting with a custom recovery ramdisk, to name a few. Historically, this functionality has been implemented in board code, making it fixed for a given U-Boot binary and requiring the code be duplicated and modified for every board. Implement a generic abstraction to run an arbitrary command during boot when a specific button is pressed. The button -> command mapping is configured via environment variables with the following format: button_cmd_N_name=

net: wget: Support non-default HTTP port

2023-12-19T13:01:59Z

Currently the wget command is hard wired to HTTP port 80. This is inconvenient, as it is extremely easy to start trivial HTTP server as an unprivileged user using e.g. python http module to serve the files, but such a server has to run on one of the higher ports: " $ python3 -m http.server -d $(pwd) 8080 " Make it possible to configure HTTP server port the same way it is possible to configure TFTP server port, using environment variable 'httpdstp' (similar to 'tftpdstp'). Retain port 80 as the default fallback port. This way, users can start their own trivial server and conveniently download whatever files they need into U-Boot.
