Hello, we realized an inconsistent implementation of fsl_get_sys_freq(): http://lxr.linux.no/linux+v2.6.29/arch/powerpc/sysdev/fsl_soc.c#L80 For 826x and 827x boards, the function is available but it cannot be used because the "bus-frequency" property is not defined for the SOC and U-Boot also does not try to do a fixup. I think that's a mistake, and the DTS files and U-Boot should be fixed, right? Furthermore, I find the name confusing. fsl_get_soc_bus_freq() would be more appropriate also to distinguish from the frequencies of the CPU. And why does the MPC52xx use a different name mpc52xx_find_ipb_freq() for that frequency? It makes support for common hardware like I2C awkward.
I haven't looked at fsl_get_soc_bus_freq(), but if the functions are duplicated, then I've got no problem changing the 52xx support to use common code. g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
