Subject: [RFC 3/5] ARM: P2V: make head.S use PLAT_PHYS_OFFSET
Date: Tue, 04 Jan 2011 20:22:57 +0000	[thread overview]
Message-ID: <E1PaDPF-00023h-V5@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20110104202052.GE24935@n2100.arm.linux.org.uk>

head.S makes use of PHYS_OFFSET.  When it becomes a variable, the
assembler won't understand this.  Switch it to use PLAT_PHYS_OFFSET
for the time being, until this code is properly updated.
