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) Fixes: FS#1484 Signed-off-by: Mason Clarke <mclarke2355@gmail.com>

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. Sunshine!
