These changes are based on this vendor tree: git.congatec.com/imx8_early_access/imx8_uboot_internal.git
Changes for v6: - fixed build warnings because of missing prototypes
Changes for v5: - fixed checkpatch errors - fixed some checkpatch warnings
Changes for v4: - fixed missing DTS file in MAINTAINERS - replaced bd_t with struct bd_info - replaced README with imx8qm-dmsse20-a1.rst - move CMD_FUSE to Kconfig - replaced power_domain_lookup_name with imx8_power_domain_lookup_name
Changes for v3: - include log.h - include delay.h - improved README - set phy register to six - Remove 'fdt_high' and 'initrd_high' environment variables - set CONFIG_SYS_BOOTMAPSZ to 256MB - increased CONFIG_SYS_FSL_USDHC_NUM to 3
Changes for v2: - added USDHC3_BASE_ADDR - replaced CONFIG_FSL_ESDHC with CONFIG_FSL_ESDHC_IMX - set CONFIG_FEC_MXC_PHYADDR to -1 - moved CONFIG_ENV_SIZE and CONFIG_ENV_OFFSET to defconfig
