+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

+ -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,

+ 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.

+/*===========================================================================
+** !!!! VERY IMPORTANT NOTICE !!!! FLASH DATA STORED IN LITTLE ENDIAN FORMAT
+**
+** This module contains the Serial Flash access routines for the Atheros SOC.
+** The Atheros SOC integrates a SPI flash controller that is used to access
+** serial flash parts. The SPI flash controller executes in "Little Endian"
+** mode. THEREFORE, all WRITES and READS from the MIPS CPU must be
+** BYTESWAPPED! The SPI Flash controller hardware by default performs READ
+** ONLY byteswapping when accessed via the SPI Flash Alias memory region
+** (Physical Address 0x0800_0000 - 0x0fff_ffff). The data stored in the
+** flash sectors is stored in "Little Endian" format.
+**
+** The spiflash_write() routine performs byteswapping on all write
+** operations.
