In order to support the coming MX6 platform and to reducde the duplicated code, we had better move some common files or functions to the imx-common folder for sharing. This patch does the following: - move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c - move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature added but just fix the checkpatch errors in the old file and remove the CONFIG_SYS_MX5_CLK32 reference in the file - create one new file cpu.c file to store the common function with i.mx5/6 Signed-off-by: Jason Liu <jason.hui@linaro.org> Cc:Stefano Babic <sbabic@denx.de> Acked-by: Stefano Babic <sbabic@denx.de>master
