android_kernel_xiaomi_sm8350/include/asm-m68k/bootinfo.h
Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

** Created 09/29/92 by Greg Harp
**
** 5/2/94 Roman Hodek:
** Added bi_atari part of the machine dependent union bi_un; for now it
** contains just a model field to distinguish between TT and Falcon.
** 26/7/96 Roman Zippel:
** Renamed to setup.h; added some useful macros to allow gcc some
** optimizations if possible.
** 5/10/96 Geert Uytterhoeven:
** Redesign of the boot information structure; renamed to bootinfo.h again
** 27/11/96 Geert Uytterhoeven:
** Backwards compatibility with bootinfo interface version 1.0
