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.

Remove obsolete support for OFILL, OFDEL, NLDLY, CRDLY, BSDLY, VTDLY,
and FFDLY which is not present on FreeBSD and not implemented in Linux.
Update #2833.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

now be configured as NULL but must instead specify the address of
the default table.

Exar 88681 but not in the base 68681.
Added support for user provided baud rate tables. This is needed
when the board does not use the standard baud rate clock.

automatic handling of RTS/CTS. This only protects the on-chip buffers
and FIFOs -- not the termios queues as the RTS/CTS code in here did. It
may be necessary in the future to enable this automatic support.
Interrupt processing code added.
In some places, channel and duart base addresses were swapped.

|
needed to properly handle the interrupt mask register since it is
shared.

Added numerous constants to mc68681_p.h.
Changed spacing.
At this point the polled support is in but nothing else is right except the
structure.

the inline implementation. The impetus for this was twofold. First,
it is incorrect to have static inline prototypes when using the macro
implementation. Second, this reduced the number of lines in the include
files seen by rtems.h by about 2000 lines.
Next we restricted visibility for the inline routines to inside the
executive itself EXCEPT for a handful of objects. This reduced the
number of include files included by rtems.h by 40 files and reduced
the lines in the include files seen by rtems.h by about 6000 lines.
In total, these reduced the compile time of the entire RTEMS tree by 20%.
This results in about 8 minutes savings on the SparcStation 10 morgana.

Configuration Table Template file added and all tests
modified to use this. All gvar.h and conftbl.h files
removed from test directories.
Configuration parameter maximum_devices added.
Core semaphore and mutex handlers added and RTEMS API Semaphore
Manager updated to reflect this.
Initialization sequence changed to invoke API specific initialization
routines. Initialization tasks table now owned by RTEMS Tasks Manager.
Added user extension for post-switch.
Utilized user extensions to implement API specific functionality
like signal dispatching.
Added extensions to the System Initialization Thread so that an
API can register a function to be invoked while the system
is being initialized. These are largely equivalent to the
pre-driver and post-driver hooks.
Added the Modules file oar-go32_p5, modified oar-go32, and modified
the file make/custom/go32.cfg to look at an environment varable which
determines what CPU model is being used.
All BSPs updated to reflect named devices and clock driver's IOCTL
used by the Shared Memory Driver. Also merged clock isr into
main file and removed ckisr.c where possible.
Updated spsize to reflect new and moved variables.
Makefiles for the executive source and include files updated to show
break down of files into Core, RTEMS API, and Neither.
Header and inline files installed into subdirectory based on whether
logically in the Core or a part of the RTEMS API.
