From a62a6e98c370ccca37d353a5f763b532411a4c14 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 11 Jan 2013 11:24:20 -0800 Subject: ARM: OMAP2+: Disable code that currently does not work with multiplaform MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We still need to fix up few places for multiplatform support, but that can proceed separately. Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.
