a9db0ea184 x86 hd image creator
A script that creates a HD image ready to be booted by an x86
emulator, ready to work in a crossbuild environment.

It's really just for qemu/kvm as there's no boot code in
the MBR and no bootloader installed so we rely on the in-kvm
multiboot implementation for now. This is very convenient for
passing args too.

To minimize reliance on external tools, we use the Minix
'partition' utility to write the partition table of the HD
image, which therefore has to be compiled natively.

	. new script releasetools/x86_hdimage.sh
	. natively compile minix 'partition' utility
	. make <machine/partition.h> 64-bit safe for it

cb5e2921b3 i2c: increase read/write timeout
The sht21 temperature and humidity sensor holds the i2c bus while
an ADC conversion is in progress. For example, a temperature
measurement is requested, a read operation is started, and the
sht21 doesn't respond to the read request until the result of
the measurement is ready. The conversion time isn't constant.
On rare occations (one in hundreds of samples) the timeout in the
i2c driver expires returning an error.

The example code from Sensirion, the sht21's manufacturer, suggests
a bus timeout of 1 second to accommodate the sht21. This commit
increases the bus timeout to 1 second. The timeout is only reached
when chips do not respond normally, so the change doesn't affect the
performance of any other drivers.

75bd3009d3 libi2cdriver: add functions for IC register access
Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.

The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.

To provide EDID to fb, the TDA19988 implements the block device
protocol with libblockdriver. To properly use the library,
blockdriver_announce() should be called by the driver.

f0c391e09b virtio-net: acknowledge used features
According to the virtio specifications, the host present the supported
features to the guest, and the guest should answer woth the features it
supports. This allows the host to disable support for features that the
guest is not going to use.

Minix tells to the host it doesn't support any extended features, while
it uses at least VIRTIO_NET_F_MAC and VIRTIO_NET_F_CTRL_VQ. For the
latter it seems it only allocate the queue while not using it later.
However starting with QEMU 1.4.0, with multiqueue support added, the
control queue is not allocated on the host side if the guest doesn't
tell it supports this feature. This cause virtio-net to crash on the
Minix side.

This patch fixes that by correctly telling the features that are
used by the Minix guest for more than printing a debug message. This
fixes virtio-net on QEMU 1.4.x.

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.

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.
