Subject: [RFC PATCH 0/4] ARM: make mach/hardware.h optional
Date: Tue, 28 Jun 2011 17:57:35 -0500 [thread overview]
Message-ID: <1309301859-17651-1-git-send-email-robherring2@gmail.com> (raw)
From: Rob Herring <rob.herring@calxeda.com>
Currently, all ARM platforms must have a mach/hardware.h include. This is
because it is ultimately included by linux/pci.h which is included in many
places even for !CONFIG_PCI.
This could be fixed simply with an ifdef around the include of mach/hardware.h
in asm/pci.h. However, in the interest of fixing this for single kernel
binary builds, this series removes the include of mach/hardware.h outside of
mach-* and plat-*. What's used from hardware.h is a couple of PCI defines.
Converting them to variables allows each platform to set the values as needed.
This does not address the inclusion of mach/hardware.h under drivers/*. This
appears to be mostly older platforms. There could also be some indirect
inclusions from other mach/* headers.
I've compile tested on most affected platforms.
