For example, printf("%+i", 1) prints "+1". However, kvprintf() did
print just "1" for this example. According to PRINTF(3):
A sign must always be placed before a number produced by a signed
conversion.
For "%+r" radix conversions, keep the "+" handling as it is, since this
is a non-standard conversion. For "%+p" pointer conversions, continue
to ignore the sign modifier to be in line with libc.
This change allows to support the ' conversion modifier in the future.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Previously, the erase ioctl call would ignore flash regions and erase at
the absolute address passed in. This adds a check for if the region is
set and adds the region offset accordingly.
This adds the possibility to open an I2C bus with O_NONBLOCK (or set it
later via fcntl) to get non-blocking transmissions. This means that if
the bus is busy, a read, write or transfer ioctl will return with a
EAGAIN errno.
The field names for the registers generated a name collision (MSR_RI on
the power pc). This patch adds a SC16IS752_ prefix for all field names.
Closes#3501.
A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.
The RTEMS_MILLISECONDS_TO_TICKS() macro doesn't round up. Do not use it
to calculate the program timeout in ticks. Check program done condition
after the timeout check to account for pre-emptions.
Update #3162.
