Modify AFU configurations for new Blue Bitstream of A10 on N3000 card:
- AFU register access: RTL changes the UPL base address and the read/write
commands of register indirect access.
- Add delays to wait for the HW reset completion.
- Refine log for debug: print UPL_version not only for vBNG bit stream,
but also for other bit streams

Fixes: c01c748e4ae6 ("net/ipn3ke: add new driver")

What means UPL?
Could you descript it in more common language?

Does HW same means with RTL?

  The debug code is moved up. Not only the version of vBNG Bitsteam, but also
  that of other bitsteams, should be printed out.

Isn't this dangerous? What do you think putting a limit to the loop?
And what do you think creating a define for 0x3?

Can you create a macro for 0x30 hardcoded value? And same for below hardcoded
values.

As far as I can see this macro is not used in this patch, why adding it?

  I will add a timeout in the loop. I will create a macro for 0x3.

Hi Dan,

Thanks your clarify, pls apply them in new patch set, not just explain them in this patch.
