Adds Support for Altera's Stratix II.
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.
