Nexus S (I902x) loaded firmwares

The various integrated circuits found on a mobile device run small pieces of dedicated software that are called firmwares, when powerful enough.
Thus, these programs do not run on the main processor: instead, they are executed on other integrated circuits.

Some firmwares come pre-installed on the integrated circuit while some others have to be loaded to the circuit by the main processor and are usually distributed along with the system.
When those firmwares are proprietary, they are not distributed along with Replicant, nor do we recommend using them.
