OK. In that case that would be better to have only one argument and 
define some flag bits for it:

#define KW_PCIE0	(1 << 0)
#define KW_PCIE1	(1 << 1)

void __init kirkwood_pcie_init(int portmask)

And usage would be:

	kirkwood_pcie_init(KW_PCIE0 | KW_PCIE1);

This is much easier to review, and less prone to errors.
