31Merge work (here and stand.i386/boot/promif) is done in July 1994.
32
331) The merge is mechanic and textual, no attempt in re-design this interface.
34   There are other projects that will replace this piece of code.
35
362) Three kind of binaries are generated:
37	#if defined(_KMDB)
38		for kmdb to use
39	#if defined(I386BOOT)
40		for booters (inetboot and ufsboot) to use and linked
41		together as libprom.a
42	#if !defined(_KMDB) && !defined(I386BOOT)
43		for kernel to use in *.o form

479 Jan, 1994:
48
49    The new plan is to do away with most of the prom lib, keeping only those
50routines that are truely common to the three prom clients (kernel, kadb, and
51second level boot).  The modules that remain are:
52
53	prom_printf.c
54	prom_getchar.c
55	prom_putchar.c
56	prom_getverion.c
57	prom_init.c
58
59Everything else (which used the 3-way #ifdef's described above), has been
60moved off into client-specific modules:
61
62	.../psm/stand/boot/i386/prom.c
63	.../psm/stand/kadb/i386/prom.c
