Explore a conference talk that demonstrates how to leverage Yocto for upstreaming, maintaining, and tracking patches in SoC and BSP development. Learn about using Yocto to create functional distros with hardware-specific changes, update to the latest kernel and u-boot versions, and manage the upstreaming process. Discover best practices for patch management using Arm's A5VE BSP as an example, covering topics such as creating bootable images, migrating to generic sources, splitting changes into patches, and effectively tracking and maintaining patches within the Yocto ecosystem.
