While we generally attempt to get rid of board specific files and replace them with device tree based descriptions, a lot of platforms have not come that far: In shmobile, we add two new board files because their recently started effort to add DT support has not proceeded enough to use it for all of the important hardware. In Kirkwood, we are adding support for new boards with a combination of DT and board file contents in multiple cases. pxa/mmp and imx are extending support for existing board files but not adding new ones. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPueuIAAoJEIwa5zzehBx3VvAP/32RkCrrLCQoibsczjwDPQir ryyT/lom005tlkXFOz9SFirlyNAn0kpDuj0xZ/HL2KgZ0FPlG0OUSRBJJvLZF2vT qlhf3PqnM1d2Ui6+/QdU/EJyzNkMAtajgTSvp4zDZayoNomO/VTZhW0feRYChUIl bJx7hnFA9VXnkhORzh9+HhKwVcdhU2R1/LMDUlYxKNnFdF0/kFgw4Gkj4MnmFlyy NpeLP4H95SeFhKPvmXB/2lZroaRn6wCxhPhUCHShxsH3YFy0J7zaEnmHMFSOX24n ++6fyb0mqiJtZPwJVbF+snb/5hP4epbmkrU5+mqtDdK8HHowAsV0ScKki0wGGmka Im5ryCMB+NZOD57XGajkpeQGZT+m0S8NilsZ5dy75o7el7WxnMLuUMyjlIbtnfet 3KRF22XnsyPuvldoej/RM1Eiz86qUFl3LPO63cYT+/c9aSw0+luMp+JZp+iOcAr3 xqyiciwOTu6CIP+DnYV72CuFa2IvLA06Eb3pgtpRUwATzS9weQ33X4Q80RaUVKxX VfXxCcDFl7dfGwqO6HujbxI6oHmEmvBEF9eGmFW2ocVrKnWUmjlC6y9tQxfReQDV SZkXKEkWPo/MLFl/AM+hTjGyu88ofOG4Vos0t3YmVyTuXekpPFb2DbPCvwnFdv8N kX/bfsxWPBDl3EdCQU8y =wkmj -----END PGP SIGNATURE----- Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull arm-soc board specific changes from Olof Johansson: "While we generally attempt to get rid of board specific files and replace them with device tree based descriptions, a lot of platforms have not come that far: In shmobile, we add two new board files because their recently started effort to add DT support has not proceeded enough to use it for all of the important hardware.
