From 01464226ac6089bd6a33f9899cc792c2355ebf39 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 28 Aug 2012 13:06:41 -0500 Subject: ARM: make mach/gpio.h headers optional Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.
