We are hardcoding 16M flash via zynq-common.h It will be good to have an option to change it at build time. It means some ifdefs there would be enough or moving it to Kconfig. Thanks, Michal

Add configuration files/dtses for mini u-boot configuration which runs on smaller footprint OCM memory. This configuration only has required parallel nor flash support.
