Is that a blob?
Yes. I think it's part of the embedded controller and someone patched the binary in order to allow fn_ctrl_swap - it doesn't seem to be able to swap them without it - although the option exists in libreboot nvramtool and does nothing.
As far as I know, embedded controller (Renesas Hitachi H8, Family 740) is ignored (not flashed) so far and there is indeed a blob. There's a Summer of Code under way to change that but it doesn't even boot the laptop yet.
By now I found binutils-h8300-hms in order to be able to assemble and disassemble the EC and I'm currently trying to find out whether the Renesas has its own flash onboard or what. I have a SOIC 16 test chip but maybe it needs another one / is SMD with insane pin count, let's see.
There was an old project called ec-18s but I don't think it's for X200. I can see https://github.com/lynxis/h8s-ec but that doesn't seem to be for X200 either.
With kind regards, Danny
