/*
 * .boot.data section contains variables "shared" between the decompressor and

 * copy over to the decompressed image before starting it.
 *
 * Each variable end up in its own intermediate section .boot.data.<var name>,
 * those sections are later sorted by alignment + name and merged together into
 * final .boot.data section, which should be identical in the decompressor and
 * the decompressed kernel (that is checked during the build).
