I don't think that's how it works. If it was =y and the select went away because of CONFIG_MACH_CCMX51=n, it remains at =y. I just tested it and that's the behavior I observed. I am not sure what we could do better here. You can use barebox as non-relocatable binary if you set CONFIG_TEXT_BASE to a sensible value. You might want this if you are keen on reducing barebox size further at cost of portability. So having a select here to ensure it's always set won't work. We can also not set a suitable CONFIG_TEXT_BASE at Kconfig level, because, due to multi-image support, we may be building different boards with different TEXT_BASEs... We could have RELOCATABLE be default y as it's a more sensible default though.
