Within your board specific init file you will have to call

1. fpga_init (/* relocated code offset. usually => */ gd->reloc_off);
2. fpga_add (fpga_altera, (Altera_desc*)&altera_desc);

Altera_desc* contines (for example):
	{
	 Altera_StratixII,	/* part type */
	 passive_serial,	/* interface type */
	 1,			/* bytes of data part can accept */
	 (void *)(&funcs),	/* interface function table */
	 0L,			/* base interface address */
	 0			/* implementation specific cookie */
	 }

funcs is the interface. It is of type altera_board_specific_func. It
looks like this:
altera_board_specific_func func = {
	pre_fn,
	config_fn,
	status_fn,
	done_fn,
	clk_fn,
	data_fn,
	abort_fn,
	post_fn,
};

you will have to implement these functions, which is usually bit
banging some gpio.

within the coming days I will submit a Patch of my own board which
demonstrate all this.

Have fun,
Liberty
