EC is an embedded controller, these are responsible for laptop charging and suspend. There are more details on the one used in OLPC http://wiki.laptop.org/go/Embedded_controller. These usually are microcontrollers (with e.g. the 8051 instruction set) that are controlled by nonfree manufacturer-supplied firmware which might be updated to fix bugs. The EC firmware practically can be considered a part of hardware, I don't know if there are updates available for the one used in the YeeLoong. (There is also e.g. the hard disk firmware; these are technically interesting.)
