Explore the evolution of SPI memory support in Linux and U-Boot in this informative conference talk. Delve into the workings of SPI memories and learn how to optimize performance using advanced SPI modes like Dual or Quad SPI. Discover the recent rework in Linux and U-Boot that enables support for various SPI memory types (SPI NOR, SPI NAND, SPI SRAM) using a unified SPI controller driver while leveraging advanced features such as direct mapping. Gain insights into the transition from small, slow SPI memories to faster SPI NOR and SPI NAND devices as primary storage in embedded systems. Follow along as the speaker, Miquèl Raynal, an embedded Linux engineer and co-maintainer of the NAND subsystem, shares his expertise on SPI memory support and recent developments in Linux and U-Boot.
