summary
A two-year status report on Linux and U-Boot flash subsystems covers improved SPI-NAND and SPI-NOR support via new MTD drivers, a matured parallel NAND API now ready for upstream, and UBIFS additions including encryption and full authentication support. U-Boot has integrated updated flash probing and erase/write flows; the update also documents found and fixed real-world regressions and memory-corruption bugs (with remaining issues tracked), and points to patches, test cases, and regression results available in upstream repositories and mailing-list threads.
