* Renamed struct timer to struct minix_timer
* Renamed timer_t to minix_timer_t
* Ensured all the code uses the minix_timer_t typedef
* Removed ifdef around _BSD_TIMER_T
* Removed include/timers.h and merged it into include/minix/timers.h
* Resolved prototype conflict by renaming kernel's (re)set_timer
to (re)set_kernel_timer.

The tool has been changed heavily to match our VND driver model.
NetBSD is in the process of renaming it from vnconfig(8) to
vndconfig(8). To keep things in sync, we have to play along.

- fail SEF initialization if any of the subtests failed, so that the
party invoking the "service up" can tell whether the test succeeded;
- add "nocontig" option, because VM isn't particularly good at
allocating contiguous memory;
- add "silent" option, because it floods the console otherwise;
- allow the device size to be smaller than the maximum transfer size;
- install files to installed test directory.

- writing to a PTY master side blocks if there is not already a
blocked reader on the slave side, and select now reflects this;
- internally, TTY now uses a test based on "caller != NONE" rather
than "grant != GRANT_INVALID" to identify whether a call is
currently ongoing;
- "offset" fields have been removed as they equal the corresponding
"cum" fields;
- improved variable typing and function naming here and there;
- various other small fixes.

- check each file descriptor's open access mode (filp_mode);
- treat an error returned by a character driver as a select error;
- check all filps in each set before finishing select;
- do not copy back file descriptor sets if an error occurred;
- remove the hardcoded list of supported character major devices,
since all drivers should now be capable of responding properly;
- add tests to test40 and fix its error count aggregation.

The T_DUMPCORE implementation was not only broken - it would currently
produce a coredump of the tracer process rather than the traced
process - but also deeply flawed, and fixing it would require serious
alteration of PM's internal state machine. It should be possible to
implement the same functionality in userland, and that is now the
suggested way forward. For now, also remove the (identical) utilities
using T_DUMPCORE: dumpcore(1) and gcore(1).

Modified the machine struct in include/minix/type.h to have an
additional field called board_id. This fields can be read out
by userland and drivers at runtime to enable automatic
configuration. The board_id field contains information about
the hardware architecture / board and such.

Minix-specific changes were needed in msg_sys.def:
* use minix_mmap()/minix_munmap() since mmap()/munmap() aren't
defined on Minix.
* use MAP_PRIVATE flag since MAP_SHARED isn't defined on Minix.
Tested with usr.bin/menuc/testm.

* increase NR_IRQ to 16 to avoid too many IRQs requested error.
* move gpio binary to /sbin (that's where mount looks for drivers).

On the AM335X, writes to the padconf registers must be done in privileged
mode. To allow userspace drivers to dynamically change the padconf at
runtime, a kernel call has been added.

The BeagleBone Weather cape enhances the BeagleBone's capabilities
by providing environment sensors (temperature, humidity, pressure,
and ambient light level).
The weatherstation demo is a port of the bonescript weatherstation
to Minix. It provides a nice visual display of the sensor data in
a web browser.
The code is installed to /usr/share/beaglebone/weather on 'earm'
and an embedded web server is started at boot time on port 80
when the cape is attached. Further details are provided in the
README.txt file.

BeagleBone Capes add additional hardware to the BeagleBone to
improve functionality.
This patch probes the third i2c bus for capes and loads the
appropriate drivers for each detected cape. Currently only
the 'BeagleBone Weather' cape is supported.

Add support for getting/setting the am335x SoC's internal real
time clock. Also, allow the power off alarm to be set.
Make readclock an "always on" driver. This is needed for setting
power-off alarms whenever the power button is pressed on the BBB.
Replace the readclock.sh script & single run driver with a
readclock program that takes the same arguments and forwards
the requests on to the always up readclock driver.

To do so, a few dependencies have been imported:
* external/bsd/lutok
* external/mit/lua
* external/public-domain/sqlite
* external/public-domain/xz
The Kyua framework is the new generation of ATF (Automated Test
Framework), it is composed of:
* external/bsd/atf
* external/bsd/kyua-atf-compat
* external/bsd/kyua-cli
* external/bsd/kyua-tester
* tests
Kyua/ATF being written in C++, it depends on libstdc++ which is
provided by GCC. As this is not part of the sources, Kyua is only
compiled when the native GCC utils are installed.
To install Kyua do the following:
* In a cross-build enviromnent, add the following to the build.sh
commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes
WARNING:
At this point the import is still experimental, and not supported
on native builds (a.k.a make build).

This program uses the i2c /dev interface to read the
contents of EEPROMs and display it to the user in
HEX and ASCII. It also has a mode that can display
data in label:value pairs. That mode is used for
board detection in the rc script to start the right
i2c drivers for the board.

-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm
Change-Id: I1b234af18eed4ab5675188244e931b2a2b7bd943
- Enable installing binutils from the base system.
- Import texinfo which is required for the binutils tools
to be compiled.
- Also adapted the fetch rules to correctly generate the
gitignore files for gcc, and allow the case of multiple
modules in the same directory, as found in gnu/dist.

. test74 for mmap functionality
. vm: add a mem_file memory type that specifies an mmap()ped
memory range, backed by a file
. add fdref, an object that keeps track of FD references within
VM per process and so knows how to de-duplicate the use of FD's
by various mmap()ped ranges; there can be many more than there can
be FD's
. turned off for now, enable with 'filemap=1' as boot option
Change-Id: I640b1126cdaa522a0560301cf6732b7661555672
Primary purpose of change: to support the mmap implementation, VM must
know both (a) about some block metadata for FS cache blocks, i.e.
inode numbers and inode offsets where applicable; and (b) know about
*all* cache blocks, i.e. also of the FS primary caches and not just
the blocks that spill into the secondary one. This changes the
interface and VM data structures.
This change is only for the interface (libminixfs) and VM data
structures; the filesystem code is unmodified, so although the
secondary cache will be used as normal, blocks will not be annotated
with inode information until the FS is modified to provide this
information. Until it is modified, mmap of files will fail gracefully
on such filesystems.
This is indicated to VFS/VM by returning ENOSYS for REQ_PEEK.

This commit removes the secondary cache code implementation from
VM and its usage from libminixfs. It is to be replaced by a new
implementation.
