T1040 and it's variants provide "Single Oscillator Source" Reference Clock Mode. In this mode, single onboard oscillator(DIFF_SYSCLK) can provide the reference clock (100MHz) to the following PLLs: • Platform PLL • Core PLLs • USB PLL • DDR PLL, etc The cfg_eng_use0 of porsr1 register identifies whether the SYSCLK (single-ended) or DIFF_SYSCLK (differential) is selected as the clock input to the chip. get_sys_info has been enhanced to add the diff_sysclk so that the various drivers can be made aware of ths diff sysclk configuration and act accordingly. Other changes: -single_src to ddr_refclk_sel, as it is use for checking ddr reference clock -Removed the print of single_src from get_sys_info as this will be -printed whenever somebody calls get_sys_info which is not appropriate. -Add print of single_src in checkcpu as it is called only once during initialization Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Vijay Rai <vijay.rai@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
