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).
