Some boards are very tight on the binary size. Booting via UEFI is possible without using the boot manager.
While I don't think we need to re-word this part, for the record my concern is global, not specific platforms. To re-iterate something we talked about on IRC, I think it's important to be able to select and have a default UEFI implementation that covers as many common use cases as possible, while also being as small as possible.
Provide a configuration option to make the boot manager available.

Select this option if you want to select the UEFI binary to be bootedvia UEFI variables Boot####, BootOrder, and BootNext. This enables the'bootefi bootmgr' command.I'm not sure this should be default y. My concern is that the default set of options is growing so that every possible case has support in the binary but the hardware and practical use means we don't need all of that. This should perhaps be "default y if DISTRO_DEFAULTS" at least.
If you want to default something to no, I think that EFI_UNICODE_CAPITALIZATION is a better candidate.

OK, thanks. Can you make up a patch with sufficient explanation of why it's OK to not support this by default?
