[PATCH v3 2/2] ARM: dts: mx51: Remove mach-cpuimx51sd board file
Fabio Estevam
fabio.estevam at freescale.com
Tue May 6 05:56:38 PDT 2014
From: Fabio Estevam <fabio.estevam at freescale.com>
eukrea_mbimxsd51-baseboard.c and mach-cpuimx51sd.c can be replaced with their
devicetree equivalents: imx51-eukrea-mbimxsd51-baseboard.dts and
imx51-eukrea-cpuimx51.dtsi respectively, so remove the board files.
This allows the conversion of mx51 to a devicetree-only platform.
