Patch from Ralf Corsepius <corsepiu@…>:

Please find enclosed a patch which enables me to build the bare-bsp for
sh-rtems.

Changes:

  1. Add preinstall to libbsp/bare/include/Makefile.in
  2. Removed FORCEIT, add preinstall to libbsp/sh/gensh1/include/Makefile.in
  3. Disabled support of set_vector from sh code (shared/setvec.c is still present but isn't used anymore), set_vector replaced with standard rtems functions.

Problems still present:

  1. Support of spin-delays in bare bsp
  2. Proper support of cpu frequency

To configure I used:

<srcdir>/configure \
--target=sh-rtems \
--prefix=<instdir>/sh-bare \
--enable-bare-cpu-model=sh7032 \
--enable-bare-cpu-cflags='-Wall -m1 -DMHZ=20
-DCPU_CONSOLE_DEVNAME="\"/dev/null\""'
--enable-rtemsbsp=bare \
--disable-networking \
--disable-cxx \
--disable-posix \
--disable-tests

IMO, if there are no objections to this patch, a similar approach should
be applied to all CPUs/BSPs (esp. hppa1.1, mips64orion, ppc403, because
they apply set_vector inside of libcpu).

3 *  NOTE: This function is considered OBSOLETE and may vanish soon.
4 *      Calls to set_vector should be replaced by calls to
5 *      rtems_interrupt_catch or _CPU_ISR_install_raw_handler.
6 *
7 *  This routine installs an interrupt vector on the target Board/CPU.
8 *  This routine is allowed to be as board dependent as necessary.
9 *
10 *  INPUT:
11 *    handler - interrupt handler entry point
12 *    vector  - vector number
13 *    type    - 0 indicates raw hardware connect
14 *              1 indicates RTEMS interrupt connect
15 *
16 *  RETURNS:
17 *    address of previous interrupt handler
