Merge tag 'omap-for-v3.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
From Tony Lindgren: Omap SoC changes. Mostly improves am33xx support, and adds minimal support for am43x SoCs. * tag 'omap-for-v3.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: AM43x: SRAM base and size ARM: OMAP2+: AM43x: GP or HS ?
