[coreboot] ThinkPad X230 with working truncated ME and 11 MB space for payload

[Marek Behun]

I have just now managed to flash my X230 with ME truncated to 828 KiB.
I used an older version of me_cleaner (commit d1abbca2). This is
because the current version of me_cleaner (which truncates ME to 96
KiB) does not work for me (X230 won't boot).

The currently active modules in my ME are (listed with unhuffme):
  BUP CLS ClsPriv FTCS HOSTCOMM KERNEL POLICY ROMP RSA SESSMGR TDT
  UPDATE

Note that originally ME contained all this modules:
  admin_cm BOP BUP CLS ClsPriv CONF_STACK eac FTCS HOSTCOMM ICC JOM
  KERNEL krb LOCL_GER MPC NET_SERVICES NET_STACK NFC Pavp PLDM POLICY
  ROMP RSA sal secio SESSMGR TDT tls UPDATE utilities WCOD_PUMA wlan

So the remove modules are:
  admin_cm BUP CONF_STACK eac ICC JOM krb LOCL_GER MPC NET_SERVICES
  NET_STACK NFC Pavp PLDM sal secio tls utilities WCOD_PUMA wlan

I do not know what all can the modules that I left there do, but my
e1000e is working.

The current layout of the flash is:

00000000:00000fff fd
000d2000:00bfffff bios
00003000:000d1fff me
00001000:00002fff gbe

This left me with 10.85 MiB for the payload.

I am attaching my current descriptor.bin and me.bin, if someone wants
to try.
