Detailed Description

struct s3c_cpufreq_board - per-board cpu frequency informatin : The SDRAM refresh period in nanoseconds. : Set if the IO timing settings should be generated from the initialisation time hardware registers. : Set if the board has external IO on any of the chipselect lines that will require the hardware timing registers to be updated on a clock change. : The maxium frequency limits for the system. Any field that is left at zero will use the CPU's settings.

This contains the board specific settings that affect how the CPU drivers chose settings. These include the memory refresh and IO timing information.

Registration depends on the driver being used, the ARMCLK only implementation does not currently need this but the older style driver requires this to be available.
