#define CONFIG_LOADADDR 0x40480000
Supported boot device types in iMX8MN: MMC, DHCP. Add DISTRO_DEFAULTS config option and include the distro boot command header file to enable full support of distro boot on i.MX8M Nano EVK (both DDR and LPDDR derivatives). Drop previous environment, which was targeting customized boot commands and boot order.
