2595 +Basic information for the AR531X Board Support Package
2596 +
2597 +This directory contains the "LBSP" -- Linux Board Support Package --
2598 +for Linux on the Atheros AR531X Wireless System-On-a-Chip. It is intended
2599 +primarily as a building block for wireless products. At this time, the
2600 +AR531X Linux BSP is experimental code, and is actively UNDER CONSTRUCTION.
2601 +
2602 +Some components that are supported by this LBSP along with a standard 2.4
2603 +Linux MIPS kernel include
2604 + R4Kc CPU
2605 + instruction and data caches
2606 + SDRAM
2607 + flash (Macronix, AMD, STS, etc.)
2608 + 16550 serial port
2609 + ethernet MACs
2610 + ethernet PHY or PHY Switch (RealTek, Kendin, Marvell)
2611 + General-Purpose I/O pins
2612 + kernel debugging with kgdb
2613 +
2614 +This LBSP code does NOT include drivers for the wireless components of the
2615 +chip/boards! Drivers for those components may be distributed separately.
2616 +In particular, the MADWiFi project under SourceForge supports (not yet!)
2617 +wireless functions on the AR531X chipset. See
2618 + http://www.sourceforge.net/projects/madwifi

2650 +There are several ways to boot a vmlinux image on an AR531X board:
2651 + -You can boot in over ethernet from the vxWorks bootrom, which is preloaded
2652 + on all Atheros boards
2653 + -You can use an ICE (e.g. VisionICE) to load the vmlinux image. You will
2654 + need appropriate register initialization (e.g. AP30.ini file)
2655 + -You can use the eCos RedBoot bootrom loader. This is a full-featured
2656 + bootrom which as been ported to AR531x. It can boot vmlinux over ethernet
2657 + or from flash. Source code is available from Atheros.

2659 +Please send comments, corrections, complaints, criticisms, suggestions,
2660 +enhancements, requests, or any other reasonable communications regarding
2661 +this effort, to "linux@atheros.com". Your email will be received by a
2662 +couple of engineers, and redirected as appropriate.

2667 + How to BUILD a linux kernel for an AR531X system
2668 +
2669 +It is expected that you will build Linux on an existing Linux system, which
2670 +has all of the standard Linux tools.
2671 +
2672 +01) Obtain a MIPS BigEndian ELF gcc-compatible toolchain. For example,
2673 + if you're cross-compiling on a x86 Linux system, you could use:
2674 + ftp://ftp.mips.com/pub/tools/software/sde-for-linux/sdelinux-5.01-4eb.i386.rpm
2675 +
2676 +02) Obtain the latest working MIPS Linux kernel
2677 + cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs login (password "cvs")
2678 + cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs co -r linux_2_4 linux
2679 +
2680 + Now "cd linux". The remainder of these instructions assume
2681 + that you are in the linux directory.
2682 +
2683 +03) Place the contents of this directory at arch/mips/ar531x.
2684 +
2685 +04) Use the patch command to patch generic linux files according
2686 + to the DIFFS directory
2687 + for i in arch/mips/ar531x/DIFFS/*.diff
2688 + do
2689 + patch -p1 < $i
2690 + done
2691 + NOTE: This version of the AR531X Linux BSP was tested with
2692 + MIPS Linux 2.4.22 as of 11/14/03. If you use a different
2693 + (e.g. more recent) version of Linux source, you may need to
2694 + resolve some minor patch and compilation issues.
2695 +
2696 +05) Set up a RAMDISK image.
2697 + See the instructions in README.RAMDISK.
2698 +
2699 +06) Set up a linux configuration using ar531x/defconfig-ar531x.
2700 + cp arch/mips/ar531x/defconfig-ar531x .config
2701 + make oldconfig (answer all questions that are asked)
2702 + NOTE: For development/debug purposes, you may want to
2703 + enable CONFIG_RUNTIME_DEBUG and CONFIG_KGDB.
2704 +
2705 +07) Make dependencies.
2706 + make dep
2707 +
2708 +08) Build the linux kernel
2709 + make
2710 +
2711 +09) The linux image you just built is in vmlinux.

2718 + How to EXECUTE a linux image on an AR531X system
2719 +
2720 +There are currently three ways to run you vmlinux image:
2721 + 1) Load it using the vxWorks bootrom that is supplied with the board.
2722 + You can load it over ethernet or from the TFFS file system, if you
2723 + have sufficient flash to store the image.
2724 + 2) Load it using an ICE (e.g. VisionICE).
2725 + 3) Use a bootrom loader, such as eCos RedBoot.
2726 +
2727 +After you have booted linux:
2728 + By default, the root filesystem on ramdisk is read-only.
2729 + To make it writable, use "mount -o remount w /".
2730 +
2731 + The user-level commands are slightly non-standard, as they
2732 + are based on "busybox".
2733 +
2734 + The "wget" command is included. You can use wget to fetch
2735 + files from any ftp server. So, for instance, you can fetch
2736 + a kernel module and then "insmod" it.
2737 +
2738 +Note that the standard source-level kernel debugger, kgdb, works well
2739 +over the serial line with this port. We use kgdb and the kgdb_demux perl
2740 +script -- available over the www -- for debugging.

3106 +** This module contains the Serial Flash access routines for the Atheros SOC.
3107 +** The Atheros SOC integrates a SPI flash controller that is used to access
3108 +** serial flash parts. The SPI flash controller executes in "Little Endian"
3109 +** mode. THEREFORE, all WRITES and READS from the MIPS CPU must be
3110 +** BYTESWAPPED! The SPI Flash controller hardware by default performs READ
3111 +** ONLY byteswapping when accessed via the SPI Flash Alias memory region
3112 +** (Physical Address 0x0800_0000 - 0x0fff_ffff). The data stored in the
3113 +** flash sectors is stored in "Little Endian" format.
3114 +**
3115 +** The spiflash_write() routine performs byteswapping on all write
3116 +** operations.
