NAK, and NAK.

Please integrate your code into the existing POST framework instead,
as a number of other boards already did.

A progress indicator may be a nice little toy, but how does it
integrate into the POST framework?

Yes, memory testing takes time. In the context of a power-on self
test (and this is what you are doing, right?) we should take care to
fit it into the existing framework, though.

Instead of integrating your needs into an existing framework you
invent yet another one. I don't want to have this, sorry.

Best regards,
