Why don't you just turn this into default __weak function and override it on
board level when it is really needed to be overridden ?
Hi Marek,
env_get_location is already declared as __weak, check env/env.c. We
can't override it 2 times.
The original version (before it was added in 2707faf01f04
("imx8mn/imx8mp: override env_get_offset and env_get_location") is
located in env/env.c and for my board, this is the preferred method.
This replacement method actually is the opposite behavior from what I
want, which is to force the environment to a fixed location regardless
of the boot device.
I think Tommaso's method is better, because as it is, the users cannot
override it any more.
Doesn't 1/4 patch break env on pretty much every single imx8m board ?
For me, patch 1/4 fixed the issue of not being able to define a fixed
environment location. It now sits where I put it. It also allows me
to boot over USB without having to define ENV_IS_NOWHERE.
Sure, it also likely breaks every other MX8M board which does not define
that env_get_location() on board level, i.e. every MX8M board.
