Subject: [PATCH v2 resend 7/9] MIPS: Move FIXADDR_TOP into spaces.h
Date: Sat, 16 Oct 2010 14:22:36 -0700	[thread overview]
Message-ID: <fe1e89d51cb25a9b6343a3dea0e8ec08@localhost> (raw)
In-Reply-To: <17ebecce124618ddf83ec6fe8e526f93@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 .
