Crochet does use the standard build machinery; the only significant =
difference is that it builds ubldr separately after a successful =
buildworld. Building ubldr separately allows it to reuse the buildworld =
results when building for multiple boards with the same TARGET_ARCH but =
varying UBLDR_LOADADDR.
The detailed logic is in lib/freebsd.sh, I=E2=80=99ve pasted it below =
(with a few variables substituted in and some error checking removed to =
clarify):
cd ${FREEBSD_SRC}
ubldr_makefiles=3D${FREEBSD_SRC}/share/mk
buildenv=3D`make TARGET_ARCH=3D$TARGET_ARCH buildenvvars`
cd ${FREEBSD_SRC}/sys/boot
eval $buildenv make UBLDR_LOADADDR=3D0x11000000 -m $ubldr_makefiles =
obj
eval $buildenv make UBLDR_LOADADDR=3D0x11000000 -m $ubldr_makefiles =
clean
eval $buildenv make UBLDR_LOADADDR=3D0x11000000 -m $ubldr_makefiles =
depend
eval $buildenv make UBLDR_LOADADDR=3D0x11000000 -m $ubldr_makefiles =
all
cd arm/uboot
eval $buildenv make UBLDR_LOADADDR=3D0x11000000 =
DESTDIR=3D${UBLDR_DIR}/ BINDIR=3Dboot NO_MAN=3Dtrue -m $ubldr_makefiles =
install
The last bit here is just a way to get the FreeBSD makefiles to copy the =
built executable to a known location (otherwise, Crochet has to =
reproduce the FreeBSD build system logic for determining which objdir =
layout to use).
Cheers,
Tim
