This should be a good starting point but leaves enough to explore yourself though: http://pastebin.com/NxVkGCdp (for version 1.02)

Updater log lines related to Syscon just after BD firmware, Multi-Card controller, BlueTooth firmware (in this case CEX 3.55) just before post processing and cleanup update status :

PS3 Retail == PS3 TEST != PS3 TOOL
I try to get PS3 TOOL SC Firmwares.

----
It is suggested that the Syscon EEPROM is 512KB and the full (encrypted) firmware is <400KB (on Ref.Tool the Syscon is updated by overwiting the whole Syscon firmware : e.g. v1.0.5c1_TMU510_u.bin  384KB)

The diag commands are usually for the backup bank, the main only supports firmud

== Updating Syscon on Tool/DECR ==

[https://cdn.anonfiles.com/1355932907234.rar v1.0.4c2_TMU510_u.bin]

'''Q: How is syscon updated on Reference Tool / DECR models?''' <br />
There are no syscon PKG's in the DECR PUPs and CP .bin file contains one large binary encrypted gibberish.
it is suggested it uses full syscon updates, but how are files like "v1.0.5c1_TMU510_u.bin" send to syscon for updating? With/via  Communication Processor?

'''A: In DECR-1000A Syscon is located on the motherboard. The Communication Processor talks to it through UART and updates it with the firmud command.'''  <br />
List of main IC's on the board:
* SCEI CXR713F120A ([[Syscon Hardware]])
* 1x Samsung K9F2G08U0M ([http://www.ps3devwiki.com/index.php?title=Flash_(Hardware) Flash] 2Gbit)
* SCEI CXD4302GB ([[Starship2]])
* SCEI CXD9790GG (?) "helps handle communication between the Communication Processor, and the system controller, and southbridge. Using this path, the CP can talk to the System Controller, and bring the system up, down, and change its boot settings."
