Subject: [PATCH] OMAP4: Move the privately used SMP boot functions to OMAP specific header.
Date: Mon, 4 Apr 2011 12:48:37 +0530 [thread overview]
Message-ID: <mailman.186.1301905263.1530.linux-arm-kernel@lists.infradead.org> (raw)
Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h
The patch is outcome of the discussion in below thread:
