-// This file defines the feature set to be compiled into busybox.
-// When you turn things off here, they won't be compiled in at all.
-//
-//// This file is parsed by sed. You MUST use single line comments.
-// i.e. //#define BB_BLAH
-//
-//
-// BusyBox Applications
-#define BB_INSMOD
-// End of Applications List
-//
-//
-//
-// ---------------------------------------------------------
-// This is where feature definitions go. Generally speaking,
-// turning this stuff off makes things a bit smaller (and less
-// pretty/useful).
-//
-//
-//
-// Turn this on to use Erik's very cool devps, and devmtab kernel drivers,
-// thereby eliminating the need for the /proc filesystem and thereby saving
-// lots and lots memory for more important things. You can not use this and
-// USE_PROCFS at the same time... NOTE: If you enable this feature, you
-// _must_ have patched the kernel to include the devps patch that is included
-// in the busybox/kernel-patches directory. You will also need to create some
-// device special files in /dev on your embedded system:
-// mknod /dev/mtab c 10 22
-// mknod /dev/ps c 10 21
-// I emailed Linus and this patch will not be going into the stock kernel.
-//#define BB_FEATURE_USE_DEVPS_PATCH
-//
-// enable features that use the /proc filesystem (apps that
-// break without this will tell you on compile)...
-// You can't use this and BB_FEATURE_USE_DEVPS_PATCH
-// at the same time...
-#define BB_FEATURE_USE_PROCFS
-
-//
-// Enable tab completion in the shell (not yet
-// working very well -- so don't turn this on)
-//#define BB_FEATURE_SH_TAB_COMPLETION
-//
-//Turn on extra fbset options
-//#define BB_FEATURE_FBSET_FANCY
-//
-//Turn on fbset readmode support
-//#define BB_FEATURE_FBSET_READMODE
-//
-// You must enable one or both of these features
-// Support insmod/lsmod/rmmod for post 2.1 kernels
-#define BB_FEATURE_NEW_MODULE_INTERFACE
-//
-// Support insmod/lsmod/rmmod for pre 2.1 kernels
-//#define BB_FEATURE_OLD_MODULE_INTERFACE
-//
-// Support module version checking
-//#define BB_FEATURE_INSMOD_VERSION_CHECKING
-//
-// Support for Minix filesystem, version 2
-//#define BB_FEATURE_MINIX2
-//
-//
-// Enable busybox --install [-s]
-// to create links (or symlinks) for all the commands that are
-// compiled into the binary. (needs /proc filesystem)
-// #define BB_FEATURE_INSTALLER
-//
-// Clean up all memory before exiting -- usually not needed
-// as the OS can clean up... Don't enable this unless you
-// have a really good reason for cleaning things up manually.
-//#define BB_FEATURE_CLEAN_UP
-//
-// End of Features List

- * Mini insmod implementation for busybox

- *
- * Copyright (C) 1999,2000 by Lineo, inc. and Erik Andersen
- * Copyright (C) 1999-2002 Erik Andersen <andersee@debian.org>
- * Written by Erik Andersen and Ron Alder <alder@lineo.com>
- *
- * Modified by Bryan Rittmeyer <bryan@ixiacom.com> to support SH4
- * and (theoretically) SH3. I have only tested SH4 in little endian mode.
- *
- * Modified by Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
- * Nicolas Ferre <nicolas.ferre@alcove.fr> to support ARM7TDMI. Only
- * very minor changes required to also work with StrongArm and presumably
- * all ARM based systems.
- *
- * Magnus Damm <damm@opensource.se> 22-May-2002.
- * The plt and got code are now using the same structs.
- * Added generic linked list code to fully support PowerPC.
- * Replaced the mess in arch_apply_relocation() with architecture blocks.
- * The arch_create_got() function got cleaned up with architecture blocks.
- * These blocks should be easy maintain and sync with obj_xxx.c in modutils.
- *
- * Magnus Damm <damm@opensource.se> added PowerPC support 20-Feb-2001.
- * PowerPC specific code stolen from modutils-2.3.16,
- * written by Paul Mackerras, Copyright 1996, 1997 Linux International.
- * I've only tested the code on mpc8xx platforms in big-endian mode.
- * Did some cleanup and added BB_USE_xxx_ENTRIES...
- *
- * Quinn Jensen <jensenq@lineo.com> added MIPS support 23-Feb-2001.
- * based on modutils-2.4.2
- * MIPS specific support for Elf loading and relocation.
- * Copyright 1996, 1997 Linux International.
- * Contributed by Ralf Baechle <ralf@gnu.ai.mit.edu>
- *
- * Based almost entirely on the Linux modutils-2.3.11 implementation.
