Currently U-Boot proper has Kconfig options that enable the generation of U-Boot binaries that are capable of being booted from the selected boot media type. The same set of generation targets for SPL are assumed with various methods and config header hackery. On some platforms the options for SPL, such as load address, are dependent on boot type and cannot depend on boot image type selected for U-Boot proper. Add a Kconfig menu to select SPL boot image types, and populate it with the same media types as are already available for U-Boot proper.
NOTE: As only a couple TI devices use make correct use of these options we limit the menu to these devices for now. The only other users of these seem to be some PPC boards that incorrectly use these as both SPL and TPL build options.
