Remove make preinstall
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.

- * Contexts
- *
- * Generally there are 2 types of context to save.

- * 2. Task level registers to save
- *
- * This means we have the following 3 context items:
- * 1. task level context stuff:: Context_Control
- * 2. floating point task stuff:: Context_Control_fp
- * 3. special interrupt level context :: Context_Control_interrupt
- *
- * On some processors, it is cost-effective to save only the callee
- * preserved registers during a task context switch. This means
- * that the ISR code needs to save those registers which do not
- * persist across function calls. It is not mandatory to make this
- * distinctions between the caller/callee saves registers for the
- * purpose of minimizing context saved during task switch and on interrupts.
- * If the cost of saving extra registers is minimal, simplicity is the
- * choice. Save the same context on interrupt entry as for tasks in
- * this case.
- *
- * Additionally, if gdb is to be made aware of RTEMS tasks for this CPU, then
- * care should be used in designing the context area.
- *
- * On some CPUs with hardware floating point support, the Context_Control_fp
- * structure will not be used or it simply consist of an array of a
- * fixed number of bytes. This is done when the floating point context
- * is dumped by a "FP save context" type instruction and the format
- * is not really defined by the CPU. In this case, there is no need
- * to figure out the exact format -- only the size. Of course, although
- * this is enough information for RTEMS, it is probably not enough for
- * a debugger such as gdb. But that is another problem.

- * least significant bits will be used.
- *
- * There are a number of variables in using a "find first bit" type
- * instruction.
- *
- * (1) What happens when run on a value of zero?
- * (2) Bits may be numbered from MSB to LSB or vice-versa.
- * (3) The numbering may be zero or one based.
- * (4) The "find first bit" instruction may search from MSB or LSB.
- *
- * RTEMS guarantees that (1) will never happen so it is not a concern.
- * (2),(3), (4) are handled by the macros _CPU_Priority_mask() and
- * _CPU_Priority_Bits_index(). These three form a set of routines
- * which must logically operate together. Bits in the _value are
- * set and cleared based on masks built by _CPU_Priority_mask().
- * The basic major and minor values calculated by _Priority_Major()
- * and _Priority_Minor() are "massaged" by _CPU_Priority_Bits_index()
- * to properly range between the values returned by the "find first bit"
- * instruction. This makes it possible for _Priority_Get_highest() to
- * calculate the major and directly index into the minor table.
- * This mapping is necessary to ensure that 0 (a high priority major/minor)
- * is the first bit found.
- *
- * This entire "find first bit" and mapping process depends heavily
- * on the manner in which a priority is broken into a major and minor
- * components with the major being the 4 MSB of a priority and minor
- * the 4 LSB. Thus (0 << 4) + 0 corresponds to priority 0 -- the highest
- * priority. And (15 << 4) + 14 corresponds to priority 254 -- the next
- * to the lowest priority.
- *
- * If your CPU does not have a "find first bit" instruction, then
- * there are ways to make do without it. Here are a handful of ways
- * to implement this in software:
- *
- * - a series of 16 bit test instructions
- * - a "binary search using if's"
- * - _number = 0
- * if _value > 0x00ff
- * _value >>=8
- * _number = 8;
- *
- * if _value > 0x0000f
- * _value >=8
- * _number += 4
- *
- * _number += bit_set_table[ _value ]
- *
- * where bit_set_table[ 16 ] has values which indicate the first
- * bit set
