Hi,

Due to very limited space in the setup_header this patch series introduces new
kernel_info struct which will be used to convey information from the kernel to
the bootloader. This way the boot protocol can be extended regardless of the
setup_header limitations. Additionally, the patch series introduces some
convenience features like the setup_indirect struct and the
kernel_info.setup_type_max field.
