Firmware Update Processes and UtilitiesChromium OS currently uses Flashrom as the firmware update tool of choice for x86, and has cross-platform ports for ARM, MIPS, and others. Flashrom is an open-source, cross-platform EEPROM programming utility with an active community and a large combination of supported host chipsets, flash memory devices, and external programmers. The code is generally adaptable to a wide variety of chipsets and interfaces and is thus a good candidate for servicing the needs of Chromium OS platforms.
