Subject: [RFC PATCH 2/7] powerpc: Permit non-zero physical start address for PPC44x
Date: Thu, 16 Jun 2011 16:14:23 +0200 [thread overview]
Message-ID: <1308233668-24166-3-git-send-email-monstr@monstr.eu> (raw)
In-Reply-To: <1308233668-24166-2-git-send-email-monstr@monstr.eu>
From: John Williams <john.williams@petalogix.com>
The initial TLB entry is 256M, meaning that the physical base address must be
256M aligned.
