The CONFIG_"_BOOT does not control anything in common code; they are mostly used to enable a set of options in include/configs/<board>.h, in other words, the behavior of these options are highly SoC specific. Actually, nothing happens for other SoCs than some TI, Freescale ones.
This menu is weird in multiple ways: [1] These options, which make sense only for TI and Freescale boards, are visible to all. The menu was place in the common place perhaps because TI and Freescale just happened to use the same config names.
[2] Multiple boot media can be enabled, and its behavior is probably undefined. This will be solved by changing "menu" to "choice". I leave this to somebody who has interest.
[3] All boot media, some of them are not supported, are visible. In fact, I do not see any reference to CONFIG_ONENAND_BOOT, CONFIG_SATA_BOOT.
This commit addresses [1]. Instead of pushing the menu away to SoC Kconfig files or somewhere, one alternative solution is to hide such a non-sense menu because it is misleading users of other boards.
