From: Tony Lindgren Date: Mon, 15 Oct 2012 19:50:46 +0000 (-0700) Subject: ARM: OMAP: Split plat/serial.h for omap1 and omap2+ X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3d82cbbb3aadb4f8a30e3f614e51be96574a0855;p=linux-beck.git ARM: OMAP: Split plat/serial.h for omap1 and omap2+ For omap1, we'll keep mach/serial.h around for 8250.c hardware workarounds. For omap2+, we no longer need mach/serial.h and can make it local to mach-omap2.
