Hey all,
Did you CC the wrong Hans by mistake?
Yeah, curse you auto-complete :S
just working on a _defconfig for our board and noticed that u-boot fails to compile if my defconfig doesn't have: # CONFIG_CMD_IMLS is not set
What supprised me is that it has to be in there as a comment to unset it. I would have imaged that it would be unset by default and only be available if set in the defconfig, or rather, how can commenting it in the defconfig unset it?
That's how Kconfig works, an option is either set =m or =y or is a comment saying "# FOO is not set", which is equivalent to the (nonexistent) =n state.
ah, well I knew that the 'non-existant' variable would take the default value, maybe I just assumed the default value should be unset :)
If a value isn't present at all then it takes on its default value, as specified in the Kconfig file (default default is off, "default y" makes it y etc), as modified by select from or depends on other options.
I'm not sure about the actual build failure. It's probably just a bug in either the code or the Kconfig, but I don't know what IMLS even is.
IMLS, IMage LiSt, but only for NOR, the NAND variant has some more letters appended :)
Ian.
I've added the u-boot list to the CC, but afaik it's not an open list and my registrations have failed on a number of occasions ...
Not that it should fail to compile either way, here's the output:
