Hi Adam,
I am going to re-do the patch for the beacon board, because I talked it over with my colleagues, and we'd like to force the environment to one location or another and not base it on whether or not it was the boot device.
I guess my questions is what's the status of the remaining patch series, and how do I integrate my desired changes into it? I can send you what I want for my board if you're going to resubmit the series.
It's ok for me. Send me your changes. Thanks.
I wonder if a sub-function could be called where the existing env_get_location() is renamed to something else, but declared as weak can called from env_get_location. Anyone who wants a their own function can write their own so we don't have two functions with the same name declared as weak.
What are your thoughts on that?
Right. In this way every boards that use imx8mp/imx8mn can override this function according to their own needs.
Tommaso
