Hi David & All,
I have successfully integrated Altera Stratix II (fast passive parallel) into the existing FPGA framework within u-boot.
so in u-boot it looks like this
==================== u-boot console ===================================== => fpga info Altera Device Descriptor @ 0x0fff474c Family: Stratix II Interface type: Fast Passive Parallel (FPP) Device Size: 1 bytes Cookie: 0x0 (0) Device Function Table @ 0x0fff255c => bunzip ff000000 200000 3c58c BUNZIP2: decompressed image address & size: 0x00200000 0x930d2c (9637164) => fpga load 0 200000 930d2c loading to fpga done. =========================================================================
I have attached two patches which are applied against the latest stable u-boot-1.1.6. The first is only the generic stuff needed for Stratix II support. The second contains my new board with a specific implementation of a Stratix II FPGA along with other add-ons and fixes
If there is any wish / demand / need to port any or all of this into the main trunk, tell me what to be done as I have never done so in the past.
here is a summery of what can be found in the patches:
u-boot-stratixII.patch : the basic generic part for Stratix II /common/altera.c : Added Altera_StratixII case /include/altera.h : Added Macros and Enums to support Stratix II /common/stratixII.c : New file that implements Stratix II based on ACEX1K.c /include/stratixII.h : New file Stratix II header /common/Makefile : Added "stratixII.o" /common/fpga.c : Added "const" to suppress warning /include/common.h : Added ndelay() declaration /include/exports.h : Added ndelay() export /lib_ppc/time.c : Added ndelay() implementation
u-boot-exsw6000.patch: contains everything in u-boot-stratixII.patch plus /board/extricom/exsw6000/config.mk : new /board/extricom/exsw6000/exsw6000.c : new /board/extricom/exsw6000/exsw6000_fpga.c : New board specific Stratix II implementation /board/extricom/exsw6000/exsw6000_fpga.h : New board specific Stratix II header /board/extricom/exsw6000/ft_board.c : new /board/extricom/exsw6000/init.S : new /board/extricom/exsw6000/Makefile : new /board/extricom/exsw6000/u-boot.lds : new /include/configs/EXSW6000.h : new /Makefile : added EXSW6000_config target /common/cmd_misc.c : Added bunzip2 command depends on CONFIG_BZIP2 macro defined /cpu/mpc85xx/cpu.c: added reset by using rstcr register depands on CONFIG_RESET_RSCTR or CONFIG_RESET_DBCR0 macro defined. The copyrights for this are not mine. I have taken it from somewhere on the net! alas I cant remember from where. :( /include/asm-ppc/immap_85xx.h: added the rstcr register in the memory map
/drivers/cfi_flash.c : added security check to prevent flash function to buffer overrun when Flash size as read from the hardware does not match the flash size define by the config file. Also added CONFIG_FORCE_FLASH_BANK_SIZE that can be used to set the Config size over the read / calculated one.
Have fun,
The forum bot admin wont let me attach my patches so i put them on yousend it... if the credits run out on some1 let me know...
