How was this tested ?
Hi Marek,
This was tested using v1 of this series after applying all patches to
the base commit referenced in that version's b4 metadata, see [1].
Tested on a Rockchip RK3576 based board with two DWC3 controllers as follows:
- Set one controller to gadget mode, the other to host mode via DT
- Confirmed no crashes or warnings in U-Boot at boot
- Initialized the host mode controller via console commands with a USB
3.0 flash drive connected via a hub
- Initialized the gadget mode controller via `ums`, pointing it at the
flash drive connected to the other controller
- Connected the gadget mode port to a Windows computer
- Confirmed no crashes or warnings in U-boot
- Confirmed the device is recognized as USB mass storage by the Windows computer
- Mounted the USB mass storage device on Windows
- Confirmed correct partitions and size
- Confirmed correct data
- Confirmed reading and writing works
- No crashes or warnings in U-boot
- Safely removed the device on Windows
- Stopped `ums` in U-boot, confirmed no crashes or warnings while stopping
This worked better than the then-current U-boot master branch, which
had trouble properly resetting the controller at boot, resulting in
non-functional gadget mode.
The TB should then be attached to 64/64 only.
