source: trunk/hal/x86_64/hal_arch.h @ 25

Last change on this file since 25 was 25, checked in by max@…, 5 years ago

First shot of the x86_64 port. It uses Multiboot V1. Most of the HAL functions
are empty, and several TSAR-specific files and comments remain; they will be
cleaned up later. The Makefile and LD script will come in another commit.
