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.
