From: Russell King Date: Tue, 4 Jan 2011 19:03:16 +0000 (+0000) Subject: ARM: P2V: avoid initializers and assembly using PHYS_OFFSET X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b75c178afaa975896e894bb2b6951dc4cd43c977;p=mv-sheeva.git ARM: P2V: avoid initializers and assembly using PHYS_OFFSET As PHYS_OFFSET will be becoming a variable, we can't have it used in initializers nor assembly code. Replace those in generic code with a run-time initialization. Replace those in platform code using the individual platform specific PLAT_PHYS_OFFSET.
