Dear Albert ARIBAUD,

Note that initialization should be unnecessary if the static variable is int rather than u8.
It should ALWAYS be not necessary.
I understand your point re: the linker warning, i.e. initializing should never be done to just get rid of a warning.
Otherwise we have a bug, and that bug needs to be fixed rather than papered over.
Yes, there is a bug whereby an u8 BSS variable causes a linker warning, and I believe this bug to be with the linker -- I'm working on getting a minimal example of it so that I could completely verify that the warning does not affect the semantics of the code generated.
Now, on an unrelated note, omap3_emv's code arbitrarily uses an u8 where an int (or enum) would be more appropriate, and this should be changed not because it removes a linker warning, but because the u8 choice is arbitrary and at best as effective as using an int, at worst suboptimal to that.
Best regards,
Wolfgang Denk
