protocol buffers with small code size.Protocol Buffers for Embedded Systems.

Nanopb is a plain-C implementation of Google's Protocol Buffers data format. It is targeted at 32 bit microcontrollers, but is also fit for other embedded systems with tight (<10 kB ROM, <1 kB RAM) memory constraints.

Making Embedded Linux Easy Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation.

The Yocto Project. It's not an embedded Linux Distribution, It creates a custom one for you. The Yocto Project (YP) is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture. The project provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations, and best practices that can be used to create tailored Linux images for embedded and IOT devices, or anywhere a customized Linux OS is needed.
