Add loader.conf to the list of files that are MD.

2017-11-13T20:39:43+00:00

loader.conf is also different between machines. On arm it's a minimal
one that's not quite compatible with the default one. On arm it's
minimal for speed, which is good, but there's also extra things in it
relative to the default on which break loading FDT which is bad. This
doesn't address that issue, but instead ensures the minimal one for
arm is used.

A similar issue for mips exists, but since we can have a beri variant
of /boot/loader and a uboot variant, I'm leaving that mess alone for
the moment.

Install the 4th files in sys/boot/forth instead of each loader

2017-11-10T23:54:58+00:00

Also, move generation of loader.help into loader.mk. Set HELP_FILES=
to disable this (so we only install one help file, for now). At the
same time remove some duplicate -I lines. Fix several FILES= and
CLEANFILES= into the += form since we're touching both of those in the
.mk files. Make sure we only build one loader.help file per platform
in a unified way (we were building many on some, with the last to
install winning, though often they were the same text).

Also, we're now installing loader.rc and menu.rc everywhere. arm and
mips uboot installed these as menu.rc.sample, but there's no need
since the loader.rc for those platforms doesn't do menu.rc processing
by default. pcibios.4th is now installed everywhere, but will failsafe
on non x86 platforms (it isn't loaded by default anywhere).

These changes are too intertwined to do separately since aspects of
each are required to have a bug-free commit.

Remove LOADER_FDT_SUPPORT as a Makefile variable.

2017-11-10T23:54:24+00:00

LOADER_FDT_SUPPORT was used inconsistently in the tree. In some
places, it was used to control whether or not the user wanted FDT
included, and in other places it was a command to include
support. Remove it entirely. The former is now enabled -DWITH_FDT,
while the latter is controlled by Makefiles defining HAVE_FDT.

loader: set options before including bsd.init.mk

2017-11-08T14:44:45+00:00

bsd.init.mk ends up including defs.mk so the per-arch options must be
set before including defs.mk, or else the global defaults will be
used and the per-arch ones will be ignored.

Although better, note that the usage of MK_FDT before the inclusion of
bsd.init.mk is incorrect but doesn't lead to build errors. This
circular dependency must be broken in order for this to work
correctly.

Remove sys/boot/arm/at91 and ixp425

2017-10-25T15:28:05+00:00

Remove at91 bootloader. It only worked on AT91RM9200, and only
specific boards that were all EOLd 10 years ago.

Remove ixp425. It doesn't build anymore and is for boards that were
EOLd 8 years ago.

Move BINDIR definition to defs.mk, and override where it isn't /boot

Use BOOTDIR consistently. We need to include bsd.init.mk early to make

Make at91 boot loader compile again.

No clue if it actually still works, but it might.

End source directories with SRC rather than a hodgepodge of names

2017-10-22T22:50:08+00:00

BOOTDIR->BOOTSRC
FICLDIR->FICLSRC
LDR_MI->LDRSRC

This matches the patterns used in the rest of the system a bit vetter.
