No problem.

Thanks for working on improving the NAND framework, and if you're
looking for other things to cleanup in this area, I have a long TODO
list, so don't hesitate to ask. Just one example: I'd like to
dynamically allocate the onfi/jedec_params [1] struct instead of
embedding them in the nand_chip struct, because this increases the size
of the nand_chip object for everyone, even for those who don't have
ONFI/JEDEC compliant chips.

This should also allow us to get rid of the onfi/jedec_version fields
(if chip->onfi_params or chip->jedec_params are NULL, the NAND is not
ONFI or JEDEC compliant and the version has no meaning, if it's not
NULL, the version can be directly retrieved from the ->onfi/jedec_params
object itself).

Regards,

Boris
