#ifndef ELF_BOOT_H
#define ELF_BOOT_H
/* This defines the structure of a table of parameters useful for ELF
* bootable images. These parameters are all passed and generated
* by the bootloader to the booted image. For simplicity and
* consistency the Elf Note format is reused.
*
* All of the information must be Position Independent Data.
* That is it must be safe to relocate the whole ELF boot parameter
* block without changing the meaning or correctnes of the data.
* Additionally it must be safe to permute the order of the ELF notes
* to any possible permutation without changing the meaning or correctness
* of the data.
