Subject: [PATCH v2 RESEND 3/7] MIPS: Move FIXADDR_TOP into spaces.h
Date: Tue, 23 Nov 2010 10:26:41 -0800	[thread overview]
Message-ID: <a3aec020607ecd552631c7ea9a5fa583@localhost> (raw)
In-Reply-To: <8a8eee995454c8b271cceb440e31699a@localhost>

Memory maps and addressing quirks are normally defined in <spaces.h>.
There are already three targets that need to override FIXADDR_TOP, and
others exist.  This will be a cleaner approach than adding lots of
ifdefs in fixmap.h .
