cp.b is used a lot as a way to load binaries to memory and execute them, however we may need to integrate this with the efi subsystem to set it up as a bootdev. So, introduce a loadm command that will be consistent with the other loadX commands and will call the efi API's. ex: loadm $kernel_addr $kernel_addr_r $kernel_size with this a kernel with CONFIG_EFI_STUB enabled will be loaded and then subsequently booted with bootefi command.

Description
|

The loadm command is used to copy memory content from source address
