Coldfire: M5271EVB: Board header update (dependencies)
Cleanup for M5271EVB: Added clarification on the use of CONFIG_SYS_CLOCK. Modified to use u-boot's HUSH parser. Cleanup on environment settings. Removed compiler warning by defining CONFIG_SYS_CS0_* Dependencies: Added the use of CONFIG_SYS_MCF_SYNCR for clock multiplier. This depends on a patch to include/asm-m68k/m5271.h that defines the multiplier and divider ratios. Removed the definition of CONFIG_SYS_FECI2C. This depends on a patch that removes the use of it in cpu/mcf52x2/cpu_init.c Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com>
