Mason Clarke 6fba88de19 ramips: reduce lzma dictionary size for D-Link DIR-645 
Currently this device fails to boot with the OpenWrt snapshot images
(release images are unaffected). The error message is:
"LZMA ERROR 1 - must RESET board to recover".

This happens because the kernel image is too big for the bootloader
to boot. This commit works around this by decreasing the lzma dictionary
size option from the default 23 to 10.

Before this change the current OpenWrt snapshot image (uncompressed
kernel size 4875139 bytes) failed to boot, while now an even bigger
image (kernel 4.19 with snapshot default config; uncompressed kernel
size 5162833 bytes) boots just fine.

The highest lzma dictionary size option this image booted with was 11.
10 was chosen to have a bit more room for growth.

An unavoidable side-effect of this change is that the compressed kernel
image will take up more space.

Total image size with different dictionary size options:
D23 - 3973903 bytes (base)
D16 - 4113167 bytes (+3.5%  - +139264 bytes)
D12 - 4317967 bytes (+8.7%  - +344064‬ bytes)
D11 - 4383503 bytes (+10.3% - +409600 bytes)
D10 - 4461327 bytes (+12.3% - +487424 bytes)

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
