+Subject: [PATCH 1/6] build: move mktplinkfw2 related commands to
+ image-commands.mk
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are already two targets (lantiq, ramips) which use mktplinkfw2
+tool for creating images. This de-duplicates code, introduces two new
+build commands: tplink-v2-header, tplink-v2-image and makes use of
+them in place of old, (sub)target specific ones.

+Subject: [PATCH 3/6] ramips: Archer C50v1: support US and EU versions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For the Archer C50v1, the EU and US versions are differentiated by their
+respective HW additional version (0x0 for US, 0x2 for EU).
+
+The stock web interface checks this field before flashing, making it
+impossible to flash the current (US) factory image on EU hardware.
+
+However the bootloader does not check this field, making it possible to use
+a single sysupgrade image for both hardware.
+
+This patch adds the necessary build bits to generate both EU and US factory
+images, and renames the target as "Archer C50v1" since there are as of now
+3 different versions of Archer C50 (all with different CPUs).

+Subject: [PATCH 4/6] firmware-utils: mktplinkfw2: support additional hardware
+ version
+
+As it turned out, some of new MediaTek based TP-Link devices use value
+from field at 0x3c offset in version 3 of TP-Link header to specify
+"Additional Hardware Version".
+
+Value from this field is validated during regular (GUI) firmware upgrade
+on devices like TL-WR840N v4 or TL-WR841N v13. If it's zero (based on
+some tests, it seems that firmware will accept anything != 0), errors
+like below are printed on console and upgrade fails:
+
+[ rsl_sys_updateFirmware ] 2137:  Firmware Additional HardwareVersion
+check failed
+
+[ rdp_updateFirmware ] 345:  perror:4506

+Subject: [PATCH 6/6] firmware-utils: mktplinkfw2: fix MD5 salt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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
