Small GPIO driver that exports a few pins using a virtual file
system. Currently the two user leds and the user button are exported.

Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.
There is also a few related Makefile updates as well as minor
source code corrections.
Replace proto.sh by the c processor to generate proto.gen in order
for us to have a more flexible way of selecting the files we want
in the ramdisk.

Also fix a potential issue where host tools would be compiled
dynamically under MINIX.
This also updates proto.common.dynamic to use the new placement
of the dynamic libraries (/usr/lib)
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
. Some Makefile fixes to automatically differentiate between a normal
compilation and cross-compilation. Also, build compressed images.
. Harmonize ramdisk rc scripts for normal use case and ext2 ramdisk.
. ext2_ramdisk filesystem prototype fixes.
WARNING: this will break existing dynamically linked binaries if they
exist. If you have any:
. re-build world statically first if necessary
. remove libraries from /lib and /usr/lib
. then build world
This change:
. avoids possible future dismay when interfacing other
systems' binaries; done until they are abi-compatible
Thanks to Antoine Leca for pointing this out.
. make ramdisk buildable without ../etc having pwd.db
. add cat to release bootstrap cmds
. support running dynamically linked executables for
release bootstrap cmds
. import netbsd chroot to help
See UPDATING about upgrading clang for dynamic linking.
. allow executables on ramdisk to be dynamically linked; this means
putting a few required shared libraries and ld.elf_so on the ramdisk.
. this makes the ramdisk (usage) smaller when they are dynamic, but
bigger when they're not.
. also we can safely ditch newroot and call mount directly as that is
all newroot does.
. create proto.common to share a bunch of entries between
small/nonsmall cases
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.
Changes in this commit:
. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
Instead of using rootdev= or ramimagedev= in the boot monitor
which are changed to numbers and cannot be used with other
loaders, rootdevname= or ramimagename= are (MINIX-style)
device names always stored as strings.
Patch by Antoine Leca.
. pre-cleanflag ("old") mkfs generates without CLEAN flag,
causing boot not working because imgrd disappears after 1st
close
. fixed sanity check for this situation
. disable imgrd disappearing in memory driver so
readonly mount succeeds in case it happens anyway
. also implement now-possible fsck -p option
. allows unconditional fsck -p invocation at startup,
only checking each filesystem if not marked clean
. mounting unclean is allowed but is forced readonly
. updating the superblock while mounted is now not
allowed by mfs - must be done (e.g. by fsck.mfs)
on an unmounted fs
. clean flag is unset by mfs on mounting, and set by
mfs on clean unmounting (if clean flag was set at
mount time)

. always compile acpi, with clang, so never have
build/clean inconsistencies; can be enabled (i.e. run
at boot time) by setting acpi variable in the boot monitor
. always strip binaries with the right strip cmd, so never
have ack/elf strip inconsistencies
Improves cache locality by grouping together dependency generation
with building for each program instead of doing a whole-tree dep
generation phase followed by a whole-tree build phase
