# Some OS-specific preliminaries for Soso.

# Memory layout
#
# 0x40000000 - 0x40001ffff - for ELF code+data
# 0x40002000 - 0x401ffffff - for heap
== code 0x40000000
== data 0x40001000

# Syscalls
#
# We don't have libc, so we need to know Soso's precise syscall layout.
# https://github.com/ozkl/soso/blob/master/kernel/syscalltable.h
