Re: [U-Boot-Users] [PATCH] Altera Stratix II support
by Wolfgang Denk 14 Apr '08

14 Apr '08

From: "eran liberty" <eran.liberty(a)gmail.com> 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.

[U-Boot-Users] [patch] disable caches before booting an app for Blackfin apps
by Mike Frysinger 14 Apr '08

14 Apr '08

It isn't generally save to execute applications outside of U-Boot with caches enabled due to the way the Blackfin processor handles caches (requires software assistance). This patch disables caches before booting an ELF or just booting raw code. The previous discussion on the patch was that we wanted to use weaks instead, but that proved to not be feasible when multiple symbols are involved, which puts us back at the ifdef solution. I've minimized the ugliness by moving the setup step outside of the main function.
