The embedded controller is a small microcontroller typically used in laptops for various purposes.
Supported by coreboot
Renesas M3885/M3886
These ECs are supported by coreboot. There are several versions, with flash and with mask ROMs. Only the flash versions are update-able. These ECs are Family 740 based. A development environment including compiler and simulator is available from Renesas.

ENE KB3310/KB3910/KB3920
Very common ECs in netbooks are the KB3310, KB3910 and KB3920 from ENE Technology. The ENE ECs are 8051 based.
The Quanta IL1 reference design seems to use ENE3310 controller. The q1d25i.rom was examined. The EC code is on 0xFFF00000 on One Mini A110. Its 64KB big HOLE0.ROM.
More discussion and info on the ENE ECs:
- ENE KB3700 datasheet.
- eeeUser Discussion
- Memory map of ENE KB3310
- 8051 simulator
- OpenEC Firmware
- OpenEC Project
- Example code that makes use of the KB3310's "Index IO" access functions.
Renesas H8
Some ECs are H8 based.
