Hi all The series adds SPL support for loading images via the MTD subsystem, including handling of bad blocks during read operations and removal of the MTD device after image loading to allow reuse by later boot stages. These changes enable SPL to load U-Boot proper from SPI NAND in a generic and reusable manner.
