Remove obsolete COMPAT_NOLABEL. It was removed >20 years ago.

Also use sti(4) ROM functions for 362/382 framebuffers on bootloader.

Mostly taken on OpenBSD/hp300.
Tested on 382 with VGA-res EVRX, and no visible regression on
425e (sti EVRX), 425t (sti CRX), and 380 (topcat).

Speed up hp300 netboot by reducing RTC access during timeout checks.

The read_bbc() function against HIL seems extremely slow.
It was being called on every timeout check via getsecs()
so it significantly slowed down loading a kernel via NFS.

In most cases (e.g., in common/if_le.c and libsa/net.c),
timeout checks are performed using getsecs() in busy loops
without any actual waiting. In such cases, it's not necessary
to read the precise time from the RTC on every call.

This change reduces the time to load the NetBSD/hp300 10.1 GENERIC kernel
via NFS from 260 seconds to 64 seconds on HP9000/382.

Bump version to denote user visible change.
Tested on HP9000/382.

Add sti(4) at sgc screen console support. From (the late) OpenBSD/hp300.

Tested on HP9000/425e, which was sent from Miod Vallat and
demonstrated at Open Source unConference 2014 Kagawa.

Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

XXX: probabry we should have bsd.saprog.mk or something.

Add dumb framebuffer (no acceleration, no colormap) support
for HP362 and HP382.

Tested on A1473-69510 (HP362 VGA-res) and A1474-69511 (HP382 mid-res).

Pull support for Tigershark monochrome framebuffer from OpenBSD.
Untested (no hardware), but doesn't break existing HP425t topcat.

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

Remove obsolete LIBSA_USE_MEMCPY and LIBSA_USE_MEMSET.

Convert mkboot into a full cross tool. Last hurdle for hp300 to building on
non NetBSD/bsd hosts.

branches: 1.24.4;
- define LIBSA_USE_MEMCPY and LIBSA_USE_MEMSET

Use 32bit daddr_t for now so that uboot.lif works again.

XXX The real fix is adding prototype declarations for all functions.

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Don't depend in libc, et al.

Add -ffreestanding to CFLAGS.

Move exec_hp300() out of uboot.c into its own file so that it can
be used by SYS_INST. SYS_INST can now boot ELF kernels inside the
miniroot.

MKfoo=no -> NOfoo

Cross-compiling of ELF bootblocks now works.

size -> ${SIZE}

branches: 1.13.2;
Convert both bootblocks and mkboot to use libsa's loadfile(), and make
both ELF aware.

Use sys/conf/newvers_stand.sh instead of local script.

Clean up the machine symlink stuff ever so slightly. Needs to be
standardized between files.

As per Chris G. Demetriou <cgd@netbsd.org> don't install
loadfile_machdep.h into /usr/include/hp300/, instead create a
link for machine and hp300 in ${.OBJDIR} like
sys/arch/alpha/stand/Makefile.buildboot does for alpha.

Optimize for space.

Include loadfile() (and a.out support for loadfile()) in libsa.

Backout my libsa changes.

No longer need to build libkern.

branches: 1.5.8; 1.5.10; 1.5.14;
convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

Eliminate bogus redefinitions of standard targets.

STRIP -> STRIPFLAG

Add support for transparent handling of decompressing read, useful
for gzip'd kernels and miniroot images.

Complete and total reorganization of the hp300 boot code, modeled
closely after the build process used by NetBSD/alpha's boot code.
