Various commands that load images have no checks that a loaded image does not exceed the available RAM space and will happily continue overwriting u-boot or other RAM that should not be touched. Also, some commands such as USB DFU or fastboot need to know the maximum buffer size, but there is no common way to define this.
Introduce a global load_size and environment variable loadsize to specify the size. The default is ~0UL which is effectively unlimited.
