Embed a multiboot header in the output executable. This is used
|
|
|
|
|
by some boot loaders (e.g., GRUB) when loading Zephyr. It is safe
|
|
|
|
|
to leave this option on if you're not sure. It only expands the

|
|
|
|
text segment by 12-16 bytes and is typically ignored if not needed.

Multiboot passes a pointer to an information structure to the

kernel entry point. Some drivers (e.g., the multiboot framebuffer

display driver) need to refer to information in this structure,

and so set this option to preserve the data in a permanent location.
