Re: [U-Boot] [RFC] Centralise documentation of CONFIG_ options (and finding unused ones)

...

From this it is easy to find unused options (CONFIG_ARIA is found only as a

#define in include/configs/aria.h for example)

So my RFC is twofold:

1. Should we start to systematically remove unused options
2. Should we centralise all options in a single README (or two, one for

standard CONFIG options and one for CONFIG_SYS options)?

Can you post data for which options are not used. While I think automatic removal is harsh, I think something close to automatic is reasonable.
