I have repeatedly objected to this patch [0][1][2] and you have
repeatedly decided to not address my objections.
or ignore your comments. I answered your questions and acknowledged
that indeed the read training was done under the dirmap handler but
this was not a concern today since we had all the required information
from spimem.
We waited _together_, 5 or 6 weeks, for more inputs on how to address
the concerns you raised regarding the sustainability of this method.
I won't spend any more time fighting it.This is not a fight. I don't know why you interpret it that way.
Now, since you object so explicitly, and since this patchset has
not reached the Linux kernel yet, we should consider dropping it.
I rather do that than push crap in mainline. But then, please,
provide solutions and not only objections !
But I will say that you should not expect any
guarantees that SPI NOR or SPI NAND will not break your calibration in
the future if they decide to move the dirmap_create() call around.
If that's the case one day, we have multiple solutions :
- stop doing the training
Not really an option, isn't it?
- move the training to the appropriate handler if it exists
Sorry for jumping in so late, but why not using this solution already
if there are concerns about the current location? It does not look like
a complex solution to implement, but I might be overlooking something.
This can also be done for the next kernel release.
