[PATCH 53/86] mips:mips_fulong2e: drop RAM size fixup

Posted by Igor Mammedov 5 years, 11 months ago

If user provided non-sense RAM size, board will complain and
continue running with max RAM size supported.
Also RAM is going to be allocated by generic code, so it won't be
possible for board to fix things up for user.

Make it error message and exit to force user fix CLI,
instead of accepting non-sense CLI values.
