Rafał Miłecki 23da3fbf68 firmware-utils: mktplinkfw2: fix MD5 salt
LEDE supports few devices using TP-Link firmware format (V2 or V3):
ArcherC20i, ArcherC50, ArcherMR200, TDW8970, TDW8980, TL-WR840N v4,
TL-WR841N v13 and VR200v

Testing mktplinkfw2 tool with official (vendor generated) firmware files
for above devices has shown an error when comparing calculated and
included MD5 sum, e.g.:
> mktplinkfw2 -i Archer_C20iv1_0.9.1_3.2_up_boot\(170221\)_2017-02-21_17.14.03.bin | grep -A 1 MD5Sum1
Header MD5Sum1         : 22 5a cb 92 10 d2 95 7b df 62 9a f8 62 17 37 10 (*ERROR*)
          --> expected : ad 19 11 d1 78 98 a7 42 5f 2e 64 da 8a 34 ec cb

This problem has been verified to occur with:
Archer_C20iv1_0.9.1_3.2_up_boot(170221)_2017-02-21_17.14.03.bin
Archer MR200v1_0.9.1_1.1_up_boot_v004a.0 Build 160905 Rel.60037n.bin
TD-W8970v3_0.9.1_2.0_up_boot(160816)_2016-08-16_10.40.57.bin
TD-W8980v1_0.6.0_1.8_up_boot(150514)_2015-05-14_11.16.43.bin
Archer_VR200vv2_0.2.0_0.8.0_up_boot(161202)_2016-12-05_14.39.06.bin

For some images, e.g.:
Archer_C50v3_EU_0.9.1_0.3_up_boot[170417-rel52298].bin
TL-WR840Nv4_EU_0.9.1_4.16_up_boot[170421-rel70692].bin
TL-WR841Nv13_0.9.1_3.16_up_boot(161012).bin
mktplinkfw2 calculates zero MD5 so these has to be fixed separately:
> mktplinkfw2 -i TL-WR841Nv13_0.9.1_3.16_up_boot\(161012\).bin | grep -A 1 MD5Sum1
Header MD5Sum1         : 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 (*ERROR*)
          --> expected : 6f 1d 9b 57 5d 42 14 6d bf a2 03 9d 46 7d 55 55

It's most likely that MD5 salt used in mktplinkfw2 has been always wrong
(and it's not a matter of e.g. a vendor change). Update it to fix MD5
calculation.

This has been also verified to calculate MD5 correctly for other (not
yet supported) devices, e.g.:
Archer_C3150v2_0.1.0_0.9.1_up_boot(160812)_2016-08-12_10.52.54.bin
Archer_C3200v1_0.9.1_0.1_up_boot(160704)_2016-07-04_15.48.28.bin

This is the buildsystem for the LEDE Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, 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.

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.
