9f4b8dc11b kernel: move do_padconf and add a test case
padconf is specific to arm, so it's being moved to kernel/arch/earm.

Add a test case to ensure the proper error is returned on non-ARM
systems.

4593804bf0 kernel: add padconf kernel call
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.

60a61dffae weatherstation: BeagleBone Weather Cape demo app.
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.

e7855d00ef rc: start drivers for attached BeagleBone Capes
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.

54f7991f4c eepromread: add board info for BeagleBone Capes
Capes (i.e. expansion boards for the BeagleBone and BeagleBone Black)
each have their own cat24c256 EEPROM with information about the cape
such as the name of the cape, pins used, power requirements, etc.

This patch adds support for displaying the cape data fields. It
can be used in shell scripts to detect and identify attached capes.

4cd78c64a4 libnetdriver: only block datalink messages
Previously, all incoming messages would be blocked before a DL_CONF
message arrives from the TCP/IP stack. This however makes it impossible
for a driver to process interrupts before the DL_CONF initialization.
This patch blocks only datalink messages before the initial DL_CONF,
and lets through all other messages to the driver.

228e84ad2a i2c: general clean-up
Implement changes based on Kees comments on the code review:
	http://gerrit-minix.few.vu.nl/#/c/676/

Changes:
 - use spin API instead of micro_delay() for busy-wait loops.
 - use read16/write16/set16 from mmio.h to access I2C registers.
 - reduce the timeout for soft reset.
 - in read/write, don't mix variable declaration and initialization.
 - after transfer, wait for access ready instead of blindly delaying.
 - rename constants am335x, dm37xx to AM335X_I2C_BUS, DM37XX_I2C_BUS.
 - rename ADDRESS_MASK to MAX_I2C_SA_MASK for clairity.
 - rename omap_i2c_claim_bus() to omap_i2c_bus_is_free().

70bd6044c8 backup: bug fix for improper struct dirent usage
Between Minix 3.1.2 and Minix 3.1.3, the d_name member of struct
dirent was reduced from 61 characters to 1 character. backup(8)
blindly copies the result of readdir() into an array of dirent
structs. As a consequence, the structs in the array only contain
the first letter of the name and the name string was not null
terminated. This caused the backup utility to always fail.

Remedy the situation by adding room for the full d_name.

039c8db774 readclock.drv: add support for the TPS65950 RTC
On the BeagleBoard-xM, the RTC is located on the Power Management IC
(PMIC). To keep things consistent, access to the PMIC's RTC is done
through the readclock driver. The readclock driver forwards the request
on to the TPS65950 driver which does the work of manipulating the
registers on the chip.

- Simplify the message passing between readclock and the driver.

 - Add a -q command line option to suppress warning messages. This
 cuts down on the noise when readclock is called early in the boot
 sequence and a secondary RTC driver (ex TPS95650) isn't up yet.

 - Update the man page to be less i386 centric and add details about
 the new -q option.

78d707cd26 VM: support for shared call mask ACLs
The VM server now manages its call masks such that all user processes
share the same call mask. As a result, an update for the call mask of
any user process will apply to all user processes. This is similar to
the privilege infrastructure employed by the kernel, and may serve as
a template for similar fine-grained restrictions in other servers.

Concretely, this patch fixes the problem of "service edit init" not
applying the given VM call mask to user processes started from RC
scripts during system startup.

In addition, this patch makes RS set a proper VM call mask for each
recovery script it spawns.
