Embedded Firmware Solutions is the perfect introduction and daily-use field guide--for the thousands of firmware designers, hardware engineers, architects, managers, and developers--to Intel’s new firmware direction (including Quark coverage), showing how to integrate Intel® Architecture designs into their plans.Featuring hands-on examples and exercises using Open Source codebases, like Coreboot and EFI Development Kit (tianocore) and Chromebook, this is the first book that combines a timely and thorough overview of firmware solutions for the rapidly evolving embedded ecosystem with in-depth coverage of requirements and optimization.

Use this book to build secure firmware.As operating systems and hypervisors have become successively more hardened, malware has moved further down the stack and into firmware. Firmware represents the boundary between hardware and software, and given its persistence, mutability, and opaqueness to today’s antivirus scanning technology, it represents an interesting target for attackers.As platforms are universally network-connected and can contain multiple devices with firmware, and a global supply chain feeds into platform firmware, assurance is critical for consumers, IT enterprises, and governments. This importance is highlighted by emergent requirements such as NIST SP800-193 for firmware resilience and NIST SP800-155 for firmware measurement.This book covers the secure implementation of various aspects of firmware, including standards-based firmware—such as support of the Trusted Computing Group (TCG), Desktop Management Task Force (DMTF), and UnifiedExtensible Firmware Interface (UEFI) specifications—and also provides code samples and use cases. Beyond the standards, alternate firmware implementations such as ARM Trusted Firmware and other device firmware implementations (such as platform roots of trust), are covered.What You Will LearnGet an overview of proactive security development for firmware, including firmware threat modelingUnderstand the details of architecture, including protection, detection, recovery, integrity measurement, and access controlBe familiar with best practices for secure firmware development, including trusted execution environments, cryptography, and language-based defensesKnow the techniques used for security validation and maintenanceWho This Book Is ForGiven the complexity of modern platform boot requirements and the threat landscape, this book is relevant for readers spanning from IT decision makers to developers building firmware

Find the right bootloader solution or combination of firmware required to boot a platform considering its security, product features, and optimized boot solutions. This book covers system boot firmware, focusing on real-world firmware migration from closed source to open source adaptation.The book provides an architectural overview of popular boot firmware. This includes both closed sourced and/or open source in nature, such as Unified Extensible Firmware Interface (UEFI), coreboot, and Slim Bootloader and their applicable market segments based on product development and deployment requirements. Traditional system firmware is often complex and closed sourced whereas modern firmware is still a kind of hybrid between closed and open source. But what might a future firmware model look like? The most simplistic boot firmware solution uses open source firmware development. This book helps you decide how to choose the right boot firmware for your products and developyour own boot firmware using open source. Coverage includes:Why open source firmware is used over closed sourceThe pros and cons of closed and open source firmwareA hybrid work model: for faster bring-up activity using closed source, binary integrated with open source firmwareWhat You Will LearnUnderstand the architecture of standard and popular boot firmwarePick the correct bootloader for your required target hardwareDesign a hybrid workflow model for the latest chipset platformUnderstand popular payload architectures and offerings for embedded systemsSelect the right payload for your bootloader solution to boot to the operating systemOptimize the system firmware boot time based on your target hardware requirementKnow the product development cycle using open source firmware developmentWho This Book Is For                                                 Embedded firmware and software engineers migrating the product development from closed source firmware to open source firmware for product adaptation needs as well as engineers working for open source firmware development. A secondary audience includes engineers working on various bootloaders such as open source firmware, UEFI, and Slim Bootloader development, as well as undergraduate and graduate students working on developing firmware skill sets.

Build your own system firmware. This book helps you understand system firmware architecture and minimalistic design, and provides a specialized knowledge of firmware development. The book includes guidance on understanding the system firmware build procedure, integrating pieces of firmware and allowing configuration, updating system firmware, creating a development infrastructure for allowing multi-party collaboration in firmware development, and gaining advanced system firmware debugging knowledge.After reading the book you will be able to assume better control while developing your own firmware and know how to interact with native hardware while debugging. You will understand key principles for future firmware development using newer technology, and be ready for the introduction of modern safe programming languages for firmware development. Detailed system firmware development case studies using a futuristic approach cover:Future scalable system firmware development modelsTypes of firmware development (system firmware, device firmware, manageability firmware)Tools and their usage while creating system firmwareHow to build infrastructure for seamless firmware development using a multi-party development modelDebugging methodologies used during various phases of firmware product developmentSetting up key expectations for future firmware, including thinner firmware footprints and faster execution time, easier configuration, and increased transparent securityWhat You Will LearnUnderstand the system firmware working model of the futureGain knowledge to say goodbye to proprietary firmware for different types of firmware developmentKnow the different types of tools required for creating firmware source code before flashing the final image into the boot device of the embedded systemDevelop skills to understand the failure in firmware or in the system and prepare the debugging environment to root cause the defectsDiscern the platform minimal security requirementOptimize the system firmware boot time based on the target hardware requirementComprehend the product development cycle using open source firmware developmentWho This Book Is For                                             Embedded firmware and software engineers migrating the product development from closed source firmware to open source firmware for product adaptation needs as well as engineers working for open source firmware development.

This book provides an overview of modern boot firmware, including the Unified Extensible Firmware Interface (UEFI) and its associated EFI Developer Kit II (EDKII) firmware. The authors have each made significant contributions to developments in these areas. The reader will learn to use the latest developments in UEFI on modern hardware, including open source firmware and open hardware designs. The book begins with an exploration of interfaces exposed to higher-level software and operating systems, and commences to the left of the boot timeline, describing the flow of typical systems, beginning with the machine restart event. Software engineers working with UEFI will benefit greatly from this book, while specific sections of the book address topics relevant for a general audience: system architects, pre-operating-system application developers, operating system vendors (loader, kernel), independent hardware vendors (such as for plug-in adapters), and developers of end-user applications. As a secondary audience, project technical leaders or managers may be interested in this book to get a feel for what their engineers are doing. The reader will find: An overview of UEFI and underlying Platform Initialization (PI) specifications How to create UEFI applications and drivers Workflow to design the firmware solution for a modern platform Advanced usages of UEFI firmware for security and manageability
