hat is the addr?
It's the payload passed to SETDASA and SETNEWDA, hence the generic
_setda suffix. addr is the new dynamic address assigned to the
device.

ority (WRT IBIs). But honestly, that's the only
use case I can think of, and to me, it sounds like an advanced feature
we may want to support at some point, but don't need in the initial
implementation.

I agree on one thing: as long as you don't have to reserve a specific
dynamic address, SETDASA is not required. At least,
it cannot be considered as utility to

We have SETNEWDA for other use cases: say you want one of your device to
have an higher priority, you can just manually set a new dynamic
address that is lower than any other devices on the bus (I plan to
ex
o take the mtd patches through the MTD
tree. As you've probably noticed, nand code has been moved around and
it's easier for me to carry those 2 simple changes in my tree than
creating an immutable branch.
Let me know if this is a problem.
