From 3c735e7437150e8615f26930c7819db85634276d Mon Sep 17 00:00:00 2001 From: eran liberty Date: Thu, 27 Mar 2008 00:50:49 +0100 Subject: Altera Stratix II support 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.
