Current U-Boot SPI NOR support (sf layer) is quite outdated as it does not support 4 byte addressing opcodes, SFDP table parsing and different types of quad mode enable sequences. Many newer flashes no longer support BANK registers used by sf layer to a access >16MB of flash address space. So, sync SPI NOR framework from Linux v4.19 that supports all the above features. Start with basic sync up that brings in basic framework subsequent commits will bring in more features.
