++How to build a ramdisk image for use as a root filesystem with AR531X
++
++Overview:
++In order to boot from a ramdisk root file system image, you will
++first create a root directory structure in the "rootdir" directory.
++Then run "make" to create a compressed root file system image in
++ramdisk.gz. Finally, copy this image into your kernel source tree
++and remake the kernel. The ramdisk image is then built into the
++kernel. When the kernel starts, it is uncompressed into RAM, and
++used as a root file system.
++
++If you'd like to use a pre-built ramdisk.gz rather than build
++one yourself:
++ cp arch/mips/ar531x/RAMDISK/ramdisk.gz arch/mips/ramdisk/ramdisk.gz
++
++Here are the detailed steps to build your own:
++
++1) Modify Makefile to point KERNEL_SOURCE at your linux source tree.
++
++2) Copy whatever additional files/directories/links you'd like to
++ under rootdir. Note that you're limited to CONFIG_BLK_DEV_RAM_SIZE
++ 1KB blocks, as specified in your linux/.config file.
++ Examples:
++ Copy busybox to rootdir/bin/
++ [NOTE: Copy busybox.links to this directory to
++ cause the makelinks script to automatically
++ set up all of the necessary busybox command links
++ in the rootdir/bin directory].
++
++ Copy any wireless driver modules into rootdir tree
++
++ You might want to make a copy of the rootdir directory
++ before you modify it, just in case you want to get back
++ to the original.
++
++3) LOGIN AS ROOT (e.g. "su") and type "make"
++
++4) Copy the resulting ramdisk.gz to your linux source tree under
++ arch/mips/ramdisk/ramdisk.gz
++ (or "make install" will do this step for you)

++Basic information for the AR531X Board Support Package
++
++This directory contains the "LBSP" -- Linux Board Support Package --
++for Linux on the Atheros AR531X Wireless System-On-a-Chip. It is intended
++primarily as a building block for wireless products. At this time, the
++AR531X Linux BSP is experimental code, and is actively UNDER CONSTRUCTION.
++
++Some components that are supported by this LBSP along with a standard 2.4
++Linux MIPS kernel include
++ R4Kc CPU
++ instruction and data caches
++ SDRAM
++ flash (Macronix, AMD, STS, etc.)
++ 16550 serial port
++ ethernet MACs
++ ethernet PHY or PHY Switch (RealTek, Kendin, Marvell)
++ General-Purpose I/O pins
++ kernel debugging with kgdb
++
++This LBSP code does NOT include drivers for the wireless components of the
++chip/boards! Drivers for those components may be distributed separately.
++In particular, the MADWiFi project under SourceForge supports (not yet!)
++wireless functions on the AR531X chipset. See
++ http://www.sourceforge.net/projects/madwifi
++
++Files included in this BSP:
++ae531xlnx.c - Linux-specific portions of the ethernet driver
++ae531xmac.c - OS-independent AR531X ethernet MAC code
++ae531xmac.h - OS-independent AR531X ethernet MAC software definitions

++README.EXECUTE - Instructions for testing your linux kernel
++README.RAMDISK - Instructions for building a root ramdisk image
++
++ramdisk.gz - A binary ramdisk image, suitable for use with AR531X.
++DIFFS - Directory that contains "patch" files (See README.BUILD)
++
++
++There are several ways to boot a vmlinux image on an AR531X board:
++ -You can boot in over ethernet from the vxWorks bootrom, which is preloaded
++ on all Atheros boards
++ -You can use an ICE (e.g. VisionICE) to load the vmlinux image. You will
++ need appropriate register initialization (e.g. AP30.ini file)
++ -You can use the eCos RedBoot bootrom loader. This is a full-featured
++ bootrom which as been ported to AR531x. It can boot vmlinux over ethernet
++ or from flash. Source code is available from Atheros.
++
++Please send comments, corrections, complaints, criticisms, suggestions,
++enhancements, requests, or any other reasonable communications regarding
++this effort, to "linux@atheros.com". Your email will be received by a
++couple of engineers, and redirected as appropriate.

++ How to BUILD a linux kernel for an AR531X system
++
++It is expected that you will build Linux on an existing Linux system, which
++has all of the standard Linux tools.
++
++01) Obtain a MIPS BigEndian ELF gcc-compatible toolchain. For example,
++ if you're cross-compiling on a x86 Linux system, you could use:
++ ftp://ftp.mips.com/pub/tools/software/sde-for-linux/sdelinux-5.01-4eb.i386.rpm
++
++02) Obtain the latest working MIPS Linux kernel
++ cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs login (password "cvs")
++ cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs co -r linux_2_4 linux
++
++ Now "cd linux". The remainder of these instructions assume
++ that you are in the linux directory.
++
++03) Place the contents of this directory at arch/mips/ar531x.
++
++04) Use the patch command to patch generic linux files according
++ to the DIFFS directory
++ for i in arch/mips/ar531x/DIFFS/*.diff
++ do
++ patch -p1 < $i
++ done
++ NOTE: This version of the AR531X Linux BSP was tested with
++ MIPS Linux 2.4.22 as of 11/14/03. If you use a different
++ (e.g. more recent) version of Linux source, you may need to
++ resolve some minor patch and compilation issues.
++
++05) Set up a RAMDISK image.
++ See the instructions in README.RAMDISK.
++
++06) Set up a linux configuration using ar531x/defconfig-ar531x.
++ cp arch/mips/ar531x/defconfig-ar531x .config
++ make oldconfig (answer all questions that are asked)
++ NOTE: For development/debug purposes, you may want to
++ enable CONFIG_RUNTIME_DEBUG and CONFIG_KGDB.
++
++07) Make dependencies.
++ make dep
++
++08) Build the linux kernel
++ make
++
++09) The linux image you just built is in vmlinux.
++ See instructions in README.EXECUTE to run your vmlinux
++ image on an AP531X-based board.

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