Again, does this ever get used?  Could you try removing it and seeing  
what happens?

I suspect it is no longer used since the change to a cacheable  
spintable.

When was CONFIG_SYS_RAMBOOT defined before, such that you need to undef  
it here?

Again, we don't need to define CONFIG_SYS_PROMPT_HUSH_PS2.  This is  
already the default, and the commit that added it as the default seemed  
to suggest that defining it in board config files at all was to be  
deprecated.

If I'm missing something, or you have some specific reason for  
continuing to leave it in, or I'm being unclear, please answer with  
that, rather than just ignoring feedback.

Please consider setting this to -1, now that it no longer disables  
compiling the auto-boot code.
