> Subject: [PATCH v2 1/2] imx8mm: configs: add support for distro boot
> commands
> 
> From: Alice Guo <alice.guo at nxp.com>
> 
> Supported boot device types in iMX8MM: MMC, DHCP.
> 
> CONFIG_CMD_PART is added for command part and
> CONFIG_CMD_FS_GENERIC is for command fstype.
> 
> CONFIG_BOOTCOMMAND which is defined in include/configs/imx8mm_evk.h
> is deleted because "run distro_bootcmd" is required to be the default boot
> mode.
> 
> scriptaddr is the location in RAM where boot.scr.uimg/boot.scr will be loaded
> to prior to execution.
> 
> kernel_addr_r is the location in RAM where the kernel will be loaded to.
> 
> Delete unnecessary environment variables.
