[DistroKit] [PATCH 0/3] Auto-Enable Android Fastboot Gadget for some boards

[DistroKit] [PATCH 0/3] Auto-Enable Android Fastboot Gadget for some boards

[Johannes Zink]

Hi,

this series configures the barebox default environment for the Radxa ROCK 3A,
AM335x Boards and STM32MP1 Boards for automatically starting an Android
Fastboot [1] and ACM USB gadget.

Android Fastboot can be used to flash the SD-Card or eMMC of the
respective boards or to load kernel, dtb and initramfs to RAM over USB.

Android Fastboot is particularly useful for loading images and development
in situations, where network boot is not a viable option.
The ACM gadget mirrors the barebox serial console over USB, which is
useful when no serial port over UART is available.

Best regards
Johannes

[DistroKit] [PATCH 1/3] v8a: rock3a: autostart usb fastboot and ACM gadget on ROCK 3A

[Johannes Zink]

This allows the board to be booted by supplying kernel, oftree and initramfs
over usb fastboot. This is particularly useful for board bringup and testing
in situations where network boot is not possible. Also, it may be used to flash
the SD card or eMMC (if fitted). While at, also improve the netboot target in
such that tftboot and nfsroot are used if available.

While at it: also autostart the ACM USB Gadget, which exposes a serial
console over USB.

The MC1 and EV1 have an eMMC, but the DK1/DK2 doesn't. Should we make mmc optional?

Nitpick: I'd have preferred emmc instead of mmc, because mmc is sometimes used
to refer to both (e.g. in the names of the barebox /dev files).

Can you enable sparse support? Flashing without it can be quite slow.
