UEFI Capsule Update for coreboot with EDK II

UEFI capsule update is an industry-standard approach widely supported by hardware vendors, providing a secure method for delivering firmware updates. By adopting capsule update methods, the project aims to simplify the update process and enhance the user experience, providing a more reliable approach compared to complex flashrom-based updates, which are still common in the open-source firmware distributions based on coreboot. Due to security measures, OS-level access to firmware is intentionally restricted, which in turn makes it increasingly challenging to apply firmware updates from the operating system. This limitation poses difficulties in utilizing traditional flashrom-based methods for firmware updates. The expected outcomes of the project include enhanced firmware update capabilities, a simplified user experience, heightened security, and enhanced compatibility, all achieved by seamlessly integrating with fwupd, a popular firmware update management tool for Linux systems.
