+The image neede to flash onto a Broadcom 63xx-series board depends on the
+board, method you are using to flash, and, for web-based flash, on the version
+of the Broadcom code your router uses.
+
+There are two major revisions of the Broadcom code as far as imagetags are
+concerned, before 3.08 and after 3.08, however there are some variations
+within in that, either due to vendor differences or due to changes at
+Broadcom (it's not clear yet which is the case). In addtion Pirelli modified
+the Broadcom code, so Alice Gate models use a different imagetag than any
+other vendor.
+
+The imagetag format for flashing via CFE is the same for almost all the
+boards, and is the same for all images generated by the imagetag utility.
+Images flashable using cfe are labelled openwrt-<board>-<filesystem>-cfe.bin
+
+The imagetags for tftp/ftp flashing is based on Broadcom 3.00-3.04 imagetags
+and is known to be correct as the source code GPL and is available for reading.
+
+Broadcom 3.00-3.02 flashing has been tested on Comtrend CT-5261, CT-536 and
+Tecom GW6000, and is the version of the flashing that was present before the
+imagetags were split by broadcom code version (early June 2009)
+
+3.04 is guessed to be the same as 3.00-3.02 based on available information
+
+Broadom 3.06 is thought to be the same as 3.00-3.02, however the only 3.06
+this author (Daniel Dickinson) has seen is the Alice Gate (Pirelli) firmware
+which is known to be different due to vendor (Pirelli) modifications to the
+Broadcom code.
+
+Broadcom 3.08 introduced changes to the imagetag to deal with TR69 (a remote
+router management system developed by the DSL Forum). The version we are
+using as 3.08 is based on the BT Voyager firmware image I looked at. It may
+in fact be BT Voyager-specific, and may in fact not be 3.08, but modified 3.06
+and not apply to all 3.08 versions.
+
+Broadcom 3.10 uses an imagetag that is believed to apply to all 3.10 and 3.12
+versions, and has been tested on the Tecom GW6200. It is similar to 3.08.
+There is a field for vendor-specific information, that at least in some cases
+is not optional. It is based on the hexedit of a neufbox4 firmware image, the
+information in https://dev.openwrt.org/ticket/4987, and the hexedit of a Tecom
+GW6200 image.
+
+Some boards share the same tag format, but require vendor-specific fields in
+the board. In that case the tagid is shared, but the filename of the generated
+image reflects the router for which the image was created.
