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.

Previously, PFS would incorrectly try to unsuspend the parent (i.e.,
the listening socket), resulting in the child hanging until the other
side performed another action. Test56 started failing on this now.

Apparently, qemu's sb16 doesn't reset the interrupt register
of the mixer and the driver ends up in an endless loop when
playing a "multi-fragment" sample.

Righ now, the DMA controller will access some random memory below 16 MB,
as the physical address returned by alloc_contig() is simply truncated
when given to the DMA controller.
Yes, it's bad...
. this is OK (although it wastes some memory) as
long as the VM interface isn't used, which has its
own checks in libsys

for clang, fix warnings in drivers/, lib/, servers/, sys/, common/.
by turning off fatal warnings (takes effect if the default is on),
fixing warnings or reducing the warning level.

. added enable interrupts routine at the HW init stage
. remove workaround, obsoleted by libnetdriver change
. change netconf.sh to allow configuring this driver,
changed README.txt to reflect this

To map kernel we use 1M sections therefore we should use
ARM_VM_SECTION_MASK to determine base address.

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.

An fprintf() has two %s formats but only one additional argument.
Include the name of the device file in the fprintf() call to
balance the arguments and format.

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().

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.

Use EDID when available to configure the frame buffer driver with
good settings for the attached display.

NetBSD provides an in-kernel EDID parser, validator, and printer
along with other useful functions. This code will be re-used by
the Minix fb driver as it is a complete and well tested
implementation.

readclock:
- the setup function for readclock on i386 was missing a return.
- the message field for RTCDEV_GRANT wasn't the right type.
tda19988:
- position variable was used without being initialized.

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.
Change-Id: I53cefbb59c5a9ab87fab90df3cc1a75a6e430f58
- 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.

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.
