Subject: [RFC PATCH 4/7] powerpc: Let simpleboot function with non zero-based memory maps
Date: Thu, 16 Jun 2011 16:14:25 +0200 [thread overview]
Message-ID: <1308233668-24166-5-git-send-email-monstr@monstr.eu> (raw)
In-Reply-To: <1308233668-24166-4-git-send-email-monstr@monstr.eu>
From: John Williams <john.williams@petalogix.com>
It is unnecessarily restrictive to fatal() if there is physical memory at a
non-zero base address.
