I don't quite follow the rationale for making these environment
variables. Wouldn't you be better off finding this info out via mtd or
sf command?
I need to use that info in a script, that's why these env vars.
Ok. Honestly, it doesn't feel quite right to me.
I haven't played with U-Boot's shell too much but is there no way to
assign variables from command outputs?
Not that I know of.
For example, can we do something
like `foo=$(cat a.txt)`? If that is possible, maybe add some new
subcommands to "sf" that return this information?
What you would want to have is per-device runtime properties, kind-of
like reduced sysfs, which would need VFS in U-Boot, and we do not have
that yet.
Are there any news on this patch ?
