660d34cd85 I2C: change BUSC_I2C_xxx to use own protocol
Previously it would use bits of the character driver protocol, which
will change heavily.  In the new situation, the BUSC_I2C_xxx requests
use a protocol more in line with the PCI protocol, with the reply code
in m_type.

20173cb5d7 TTY: fix for PTY open/close logic
Opening and closing the master side of a pseudo terminal without
opening the slave side would result in the pseudo terminal becoming
permanently unavailable.  In addition, reopening the slave side
would be possible but not allow for I/O.  Finally, attempting to
open an in-use master would wipe its I/O state.  These issues have
been resolved.

97172a1db0 Sync char protocol: add nonblocking transfer flag
The async char protocol already has this, so this patch closes the
gap between the two protocols a bit. Support for this flag has been
added to all sync char drivers that support CANCEL at all.

The LOG driver was already using the asynchronous protocol, but it
did not support the nonblocking transfer flag. This has been fixed
as well.

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.

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.

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().

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.

437177b028 i2c: increase BUFLEN/CMDLEN to 128, add page flag.
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).

80846c4a79 kernel ipc debug: various fixes
. add receive hooks in the kernel to print asynchronously
	  delivered messages
	. do not rely on MF_REPLY_PEND to decide between calls and errors,
	  as that isn't reliable for asynchronous messages; try both instead
	. add _sendcall() that extract-mfield.sh can then reliably recognize
	  the fields for messages that are sent with just send()
	. add DEBUG_DUMPIPC_NAMES to restrict printed messages to
	  from/to given process names

037aeb5a13 arm:rs232 fix.
The kernel API for requesting interrupts and the associated callback
have a somewhat strange behaviour. Requesting an interrupts is done
by calling sys_irqsetpolicy using an interrupt and a given id. This
id can be modified by the sys_irqsetpolicy and must be used for
subsequent calls to sys_irqenable/sys_irqdisable. However upon an
incoming call from the kernel NOTIFY_ARG contains the original value
encoded in a set e.g. if  1 << id == true the interrupt was raised.

e67fc5771d libc: add clock_getres()/clock_gettime() system calls.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().

Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.

System calls clock_getres() and clock_gettime() were added to PM/libc.

5acaa0814f kernel, ramdisk: some boot unification
To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.

This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.

	. ramdisk: remove some arm-only utilities only used for running
	  from the shell
	. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
	  boot-time ramdisk files
	. change kernel to add "arch" variable so userland knows what
	  we're running on from sysenv
	. make ARM use the regular ramdisk rc file, changed to distinguish
	  i386-only and ARM-only drivers; requires rootdevname to be set
	. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
	  i386 systems
	. change the kernel/arm to have a special case for the memory
	  driver to load it higher so it can be bigger
	. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
	  SD preparation script arm_sdimage.sh to the git repository in
	  releasetools/

8f3fbf7cc1 Cleanup: Remove minix.bootprog.mk
The build system distinction between "bootprog" and "service" is
meaningless as boot programs are standard services.

As minix.service.mk simply imports minix.bootprog.mk, reduce confusion
by removing minix.bootprog.mk and placing the rules in minix.service.mk.

ba49a155b5 fb: introduce framebuffer support to Minix
This patch introduces a framebuffer to Minix. It's written for the ARM
port of Minix, but has an architectural split that separates the
hardware dependent part from the non-hardware dependent part. Futhermore,
this driver was developed using a screen that has a native resolution of
1024x600 pixels and having lack of support for obtaining EDID from the
screen. Consequently, it uses a hardcoded resolution of 1024x600.

The driver uses an interface based on the Linux ioctl API, but supports
only a very limited subset.

9d89e72a5c ahci: more robustness against flaky devices
- if supported, override BSY/DRQ flags and start the port anyway if it
  times out with DET=3h status during device detection;
- no longer rely on the device signature to be set; unless a valid
  signature is obtained, try both ATA and ATAPI device identification.

eb89b33d39 ahci: device detection rewrite
- do not start a port before the BSY and DRQ flags have been cleared;
  as such, poll on device status rather than signature availability.
- change "ahci_sig_timeout" to "ahci_device_timeout" variable setting
  accordingly; this variable determines the polling duration before a
  newly attached device is given up on, and uses 30 seconds as default;
- use port connect changes (PCS/X/DET->1h) to kick off polling for an
  attached device; detachment is still detected by means of PhyRdy
  status changes (PRCS/N/DET<->3h).

- timeout values are no longer used for both millisecond and clock
  tick values, and better typed;
- the computation of timeouts is no longer off by half a second.
