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.

This header is used also by the motorola_powerpc BSP.
Update #3254.

The name suggests that this is a private implementation header file.
Update #3254.

This header file contained timing overhead values which are hard to
maintain.

This first step eliminates the following as public APIs for the pc386
BSP:
+ pcib_conf_read8
+ pcib_conf_read16
+ pcib_conf_read32
+ pcib_conf_write8
+ pcib_conf_write16
+ pcib_conf_write32
The if_fxp.c driver uses these enough where I provided local macros
to allow the code to be mostly unmodified. On other architectures
these names have been used privately. It will take multiple patches
to completely eliminate these symbols from the RTEMS source tree.
The focus of the first effort is just to eliminate these as a public
pc386 API so support can be added for systems without legacy PCI BIOS.

basic VGA driver can be enabled during configure phase by exporting variable
USE_VGA=1 so that it is available in configure environment
cirrus driver is enabled the same way by exporting variable
USE_CIRRUS_GD5446=1

driver is not initialized by default
initialization is possible through multiboot command line option or
through the string variable (see fb_default_mode.h) set in user's module
allowing the driver to evaluate this variable after the two
modules are linked together

The current support for the Edison supports a single polled
UART for input and output plus a simulated clock tick. The
activities forward for supporting the Edison have been posted
on the RTEMS mailing lists and at:

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.

With this patch the preinstall.am files are in a set order and not
dependent on now perl implements a hash.
