Board-related updates. This branch is getting smaller and smaller, which is the whole idea so that's reassuring. Right now by far most of the code is related to shmobile updates, and they are now switching over to removal of board code and migration to multiplatform, so we'll see their board code base shrink in the near future too, I hope. In addition to that is some defconfig updates, some display updates for OMAP and a bit of new board support for Rockchip boards. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJSgBsmAAoJEIwa5zzehBx3m3oP/ingw9VE69O3GLjd2zWI35HJ +NuFmwlWFj+1XLysfCxHJn3rvkMJKM33ZcP6FkgJGMHfQRRBmrC0REG/nQq59riE c7R+Jguw044kAGH3evg4kCJ3gI+WD+H+juKf4IQ9bYDaneZGN9f0hkuzLRbmqwZP RIDa+q+Oo6Q3pcTUvkz2lMV6q7Ydb5H49suyPN+9muJ1wVYjFR+XuvnYzy/PO2lF kyIN2fijQN278QjM6eZEtsFoB7L7NmuZr8ZBTkekHSfybqIsb59JEqZER7huJSdR fEk0VQ/A6M2LQSRTL+UrCadFYaxDnW8wjxbpLUikhg7ONnrCBSGvVj4nFiEKAFdE R49YZ2hqhrXjie1kGoKuXGmxGG/7ODJWmWDgnIXx0daSOgPUomlO8YKtGeBO1/Zf 6wsvAjiukcLV10JEF/rCslTEA/Ck5dJZjV6S/8hSy1N+CF4qZflSmXG0gb9tB+nv ztRN9gTlJSr/MpIE3jpbPFxNwef+UPW/R8fnO7fdnzPeOpwTDzZ1ydArC0IIpmgt Ngum5iyP4qcwZ91hWXhdAu3ZGeHWZ5tox1W/DMjkyTxCEDUUdtfkChOGf/Wmjg7z Rl5nyH2Y4xT0+Otn/0LIqKvEh1JwwX9FlIqkJI4IMrnYJwHQ4oBvOAGskW1ZsFPQ 0OBbAAHS1tio3ZywNMIQ =ZYOa -----END PGP SIGNATURE----- Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC board updates from Olof Johansson: "Board-related updates.
