[PATCH v5 51/79] mips/mips_fulong2e: drop RAM size fixup


From: Igor Mammedov
Subject: [PATCH v5 51/79] mips/mips_fulong2e: drop RAM size fixup
Date: Mon, 17 Feb 2020 12:34:24 -0500

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.

v2:
 * fix format string cousing build failure on 32-bit host
   (Philippe Mathieu-Daudé <address@hidden>)
v3:
 * since size is ifxed, just hardcode 256Mb value as text
   in error message
   (BALATON Zoltan <address@hidden>)
