Nice to see that idea implemented! For me though, changing any of the
U-Boot variables is out of the question, and I need the matcher just the
way I implemented it, including the LED blink pattern to let the user
know if things go wrong.
Hence, I won't change to your generic version on my boards, and so I
think it might be best if you maintain your own tree for your approach.
Best regards,
Daniel
