I'm a bit lost at the logic of this last sentence. If errors are not
always represented as negative return values, and especially so in
U-boot, then what is the rationale for supporting a request for
specifically negative error return values, rather than positive, here?
Not that I mind much -- as I said, ide_init() does not mind, and that's
my reference -- and I'll happily put negative error codes in V3, but I
like to understand why people want things.
Amicalement,

Albert.
