The Coverity issue was an ignored return value from a read()
in a loop which should have been a seek() since the data
read was ignored.
The file itself needed reformatting to conform to RTEMS style.
This allows the BSP to define an optional spin delay which is
useful for making time appear to pass at a rate closer to
wall time. On the Edison, this was used with a polled console
driver to slow polling to a reasonable rate and make time
pass reasonably close to correctly even with no clock tick
support.
This allows the support for the legacy COM1-COM4 serial ports
to be completely disabled. It is needed to prevent hangs on some
hardware. In particular, the Intel Edison where it is not present.
This allows the IDE support to be completely disabled. It is needed to
prevent hangs on some hardware. In particular, the Intel Edison where
it is not present.
This allows the VGA and keyboard console to be completely disabled.
It is useful on PCs without displays and prevents a very slow boot
time on the Intel Edison.
The current algorithm scans all PCI busses (0..ff)
and all devices (0..31) on each bus for bridges
and determines the maximum of all subordinate
busses encountered.
However, the algorithm does not scan all functions
present in multi-function devices -- I have a PCI express
root complex (82801H) where multiple (non-zero index)
functions are 'PCI bridges' whose subordinate bus number is
missed by the original algorithm.
This commit makes sure that the scan
is extended to all functions of multi-function
devices.
See #2067
rtems_dhcp_failsafe() can be configured at compile time with
various options. This change makes it possible to instead configure
it at runtime.
This will make it marginally larger. I haven't measured the difference
but I'll guess it's in the lower hundreds of bytes. The change could be
modified to leave it either compile time or run time configurable,
I prefer the simplicity of a single method.

The previous timeout handling was flawed. In case a waiting thread
helped out the owner could use the scheduler node indefinitely long.
Update the resource tree in _MRSP_Timeout() to avoid this issue.
Bug reported by Luca Bonato.
Some file systems do not support sync() at all and return an
error indicating this on any sync() call. In particular, the
IMFS is one of these and thus this assertion is tripped in
normal testing.
Since sync() is void per POSIX, the error just must be ignored.
The dummy.c was a de-facto default configuration. Rename it to
default-configuration.c. Use unlimited objects and the stack checker.
This makes it easier for new RTEMS users which will likely use this file
if they just work with the usual main() function as the application
entry point. Provide proper arguments for main() using the BSP command
line. Add spare user extensions and drivers.
Do not initialize the network by default. Delete bspinit.c.
On recent u-boots, the watchdog is turned on / left enabled. The
Beaglebone Black rev. C ships with such a u-boot internally so any
application booting from it must disable the watchdog.
Therefore this change is needed to boot an RTEMS app out-of-the-box
on a BBB Rev C - otherwise the user button must be held during boot
(to bypass the stock uboot) or the internal uboot must be updated. To
allow for a better out-of-the-box experience, we just turn off the
watchdog.
