+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+
+# You can get the latest version of this script from:
+# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.

+ *  Changes by Clifford Wolf (god@clifford.at)
+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set 
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different OpenWrt configurations.\n"
+"\n"
+"At the end of the main menu you will find two options.  One is\n"
+"for saving the current configuration to a file of your choosing.\n"
+"The other option is for loading a previously saved alternate\n"
+"configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you\n"
+"find during a Menuconfig session that you have completely messed\n"
+"up your settings, you may use the \"Load Alternate...\" option to\n"
+"restore your previously saved settings from \".config\" without\n"
+"restarting Menuconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use Menuconfig in an XTERM window make sure you have your\n"
+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, Menuconfig will look rather bad.  Menuconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry.  I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment.  Some distributions\n"
+"export those variables via /etc/profile.  Some ncurses programs can\n"
+"become confused when those variables (LINES & COLUMNS) don't reflect\n"
+"the true screen size.\n"
+"\n"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the build options listed in a single\n"
+"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
+"with MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"

+#
+# i.e. the flash layout is:
+#
+# 90000000-9000FFFF mtd2 bootloader
+# 90010000-9001008F ---- firmware signature )
+# 90010090-90090FFF mtd1 kernel             ) mtd4 spans these three regions
+# 90091000-903EFFFF mtd0 filesystem         )
+# 903F0000-903FFFFF mtd3 config space
+#
+# The ADAM2 bootloader uses the mtd1 settings to find the start of the image to boot.
+# The image to load contains information about the loadable size of the image. If ADAM2 sees
+# that the image appears to extend beyond the end of mtd1, it will refuse to load it. On
+# the DSL-502T, this manifests as the USB light blinking rapidly on boot.
+#
+# The OpenWRT kernel does not follow quite the same layout:
+#  (a) it does not have a 0x90-byte firmware signature prefix
+#  (b) it is larger than the default mtd1 size
+#
+# (a) would be avoidable (build a custom image with a 0x90-byte prefix) but (b) is unavoidable.
+# So we *have* to change mtd1. The simplest thing to do seems to make it span all of
+# the flashable area, producing this layout:
+#
+# mtd0 0x90091000,0x903f0000    # filesystem
+# mtd1 0x90010000,0x903f0000    # kernel (CHANGED)
+# mtd2 0x90000000,0x90010000    # bootloader - DO NOT MODIFY
+# mtd3 0x903f0000,0x90400000    # config space - DO NOT MODIFY
+# mtd4 0x90010000,0x903f0000    # kernel + filesystem, used to flash new firmware
+#
+# *** NOTE NOTE NOTE NOTE ***
+#
+# /dev/mtd0 .. /dev/mtd4 when using OpenWRT do **NOT** correspond to the ADAM2 mtd0-4 settings!
+# Instead, OpenWRT scans the MTD itself and determines its own boundaries which are arranged
+# quite differently to ADAM2. It will look something like this, see dmsg on boot:
+#
+# (/dev/mtd0) 0x00000000-0x00010000 : "loader"        # Bootloader, read-only
+# (/dev/mtd1) 0x003f0000-0x00400000 : "config"        # Config space
+# (/dev/mtd2) 0x00010000-0x003f0000 : "linux"         # Firmware area (kernel + root fs + JFFS area)
+# (/dev/mtd3) 0x000d0d58-0x003f0000 : "rootfs"        # Root FS, starts immediately after kernel
+# (/dev/mtd4) 0x00280000-0x003f0000 : "rootfs_data"   # If rootfs is squashfs, start of JFFS area.
+#
+# All of those boundaries are autodetected by examining the data in flash.
