Some ARM chips handle power-off with RTC alarms. PM notifies
readclock (the driver for RTCs) about the impending power-off.
If the power-off mechanism is an RTC alarm, readclock will
set the alarm. If not, there is no effect.

AM335X SoCs support power-off via a power management
chip (PMIC). An alarm in the real time clock is used
to trigger the PMIC to cut the power.
To ensure the alarm goes off when the system is in
a safe state, the RTC is frozen when the alarm is
set. At the last moment, the kernel unfreezes the RTC
to let the alarm go off.
This patch adds a mini driver for unfreezing the RTC
as well as code to handle RBT_POWEROFF on Minix/arm.

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.

128 byte reads are much more common than 32 byte reads. The message
passing + setup/teardown for a read is much more expensive, in terms
of time, than the reading itself. A slightly bigger struct is well
worth the time savings. This reduces read times for /dev/eeprom
from 57 seconds per 4KB to 14 seconds.
Additionally, make sending the page address in the eeprom driver
and utility optional. This can save a little time when reading
within the same page and allows support for smaller devices that
don't support pages (example: chips containing EDID).

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.

The padconf library runs in user mode, but to actually affect the
padconf register contents, the processor has to be in privileged
mode. A full server based solution will be developed, but for now
just set the pinmux in the kernel at boot.

- use the proper make variable to ignore file lists
SLOPPY_FLIST instead of CHECKFLIST, which was a minix hack.
- Add BUILDOPTIONS such that the users can activate optional
features without editing the script.

-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.

. modules can be as big as the space (8MB) between them
instead of 4MB; memory is slightly bigger with DBG=-g
arm ucontext:
. r4 is clobbered by the restore function, as it's
used as a scratch register, causing problems for the
DBG=-g build
. r1-r3 are safe for scratch registers, as they are
caller-save, so use r3 instead; and don't bother
restoring r1-r3, but preserve r4
