This is confusing and we almost broke the nand support again recently after converting the platform to common clock framework (which changed the device id in the clock lookup - the problem is gone now that we no longer acquire the clock in the nand driver. This patch adds a new filed - core_chipsel - to the platform_data. Subsequent patches will convert the platforms to using this new field.
