d1bdfb40fd -ffreestanding is the word. 
(also resort some CFLAGS such that the more "important" value are first so
they are easier to see)

127e8646b8 Split file system setup code out into a function called mount. 
Implement vsnprintf.  Implement panic in terms of it.

0d0c927680 Add support for loading files other than /boot/loader. Useful if you're 
loader is screwed and you want loader.old.
Rewrite the scaled down printf so it actually works right, and add support
for more formats.

4b487ad2ec Clean up elf loading to not make assumptions about the ordering of sections. 
Don't load the symbol table; this is only needed for loading kernels and we
load the loader.

912ceb7f18 Remove a bunch of unused variables, functions and macros. Allocate storage 
statically instead of using a faked up malloc.

2c94cd1ba0 1.) Rename locore.s to locore.S (by repocopy), to be able to remove 
special-case make rule
2.) Cleanups, remove superfluous expicit rules, add -nostdlib to LDFLAGS,
    remove -X and -g, remove -g from CFLAGS
3.) Add BINDIR
4.) Build install the loader help file, add an empty help.sparc64
5.) Change the default configuration to only support booting from disk
6.) Get libofw.a from a path relative ${.OBJDIR}, not ${.CURDIR}

20d9715213 Apparently either gcc or ld, in their infinite wisdom, want to 
put a bunch of crap before the code in .text.  Since the firmware
doesn't seem to honour the a.out entry point, we need to include
a little assmbler file which jumps to where we want to be in C.

4aaca88542 Keep track of the ttes used to map the kernel and pass them to it as loader 
metadata.  Modify tlb handling functions to take a tte, instead of virtual
address, physical address and flags.

3c5ef798a0 Add make variables for fs support and propagate them to CFLAGS. Put 
-ffreestanding in CFLAGS.  Remove unnecessary LDFLAGS.

d112f7bd5b Fix fs support ifdefs. Add tftp support. Add physical and virtual 
watchpoint support for debugging (under LOADER_DEBUG).  Claim the
physical and virtual addresses used to map the kernel from the prom;
we map it ourselves behind the scenes though.  Add a reboot command.

073e92a52c Use ENTRY() for defining functions in asm. 
Remove asm functions to call the openfirmware and kernel entry points;
we can just call them directly.
Don't use the stack pointer for an intermediate result in setx.
Put the stack in the bss.
