/*
 * The kernel boot info, that will be passed
 * to the main kernel file
 * NOTE: the structure is similar to x86_64 build and
 * arm64 build. This structure was designed only for
 * UEFI based boot protocol. But LittleBoot doesn't
 * use UEFI, so it has to somehow prepare the same structure
 * and passed to the kernel, because kernel was already
 * build from ground up with UEFI in mind. Most of the
 * fields are not used though, but little boot uses
 * its own structure for the kernel and pass it through
 * the main structure, kernel can recognise little boot
 * structure
