Jo-Philipp Wich 731543f24d ar71xx: fix mtdpartsize macro in image Makefile (#14961)
The mtdpartsize macro triggers shell errors on various Linux distributions
when the partname argument $(1) does not appear within the partmap $(2).

Change the sed pattern to only emit anything if a successful substitution
occured and only evaluate the arithmetic expression if something was printed
by the sed program.

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl
make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.


Sunshine!
