building FreeBSD/arm64 VM images and memstick.img installation
medium:
r281786, r281788, r281792:
r281786:
Add support for building arm64/aarch64 virtual machine images.
r281788:
Copy amd64/make-memstick.sh to arm64/make-memstick.sh for
aarch64 memory stick images.
Although arm64 does not yet have USB support, the memstick
image should be bootable with certain virtualization tools,
such as qemu.
r281792:
Add a buildenv_setup() prototype, intended to be overridden as
needed.
For example, the arm64/aarch64 build needs devel/aarch64-binutils,
so buildenv_setup() in the release.conf for this architecture
handles the installation of the port before buildworld/buildkernel.

xz(1) compression of the virtual machine images.
This is intentionally separate to allow more fine-grained
tuning over which images are compressed, especially in cases
where compressing 20GB sparse images can take hours.

Connect the virtual machine image build to the release
target if WITH_VMIMAGES is set to a non-empty value.
release/release.sh:
Add WITH_VMIMAGES to RELEASE_RMAKEFLAGS.
release/release.conf.sample:
Add commented entries for tuning the release build if the
WITH_VMIMAGES make(1) environment variable is set to
a non-empty value.

r269549:
Create a new project branch, release-noxdev, for
a sandbox workspace outside of head/ to update the
release bits for arm builds since the deprecation of
the XDEV and XDEV_ARCH make(1) variables.
r269551:
Define load_chroot_env() and load_target_env()
prototypes.
r269552:
Call load_chroot_env() and load_target_env() where
they can be mutually conflicting with regard to
TARGET, TARGET_ARCH, XDEV, and XDEV_ARCH.
r269553:
Add shebang line to arm/*.conf files since these
should be considered to be executable (albeit not
on their own) shell scripts.
r269554:
Redefine load_chroot_env() and load_target_env() in
the arm/*.conf files, and reindent.
r269555:
Simplify where load_chroot_env() and load_target_env() are
called.
r269558:
Provide example in release.conf.sample for overriding the
load_chroot_env() and load_target_env() prototypes.
r269559:
Remove a gratuitous newline.
r269560:
Unset potentially conflicting variables in load_chroot_env()
and load_target_env().
r269561:
Make global variables global, and accessible outside of
the functions within which they were once defined.
r269628:
Remove XDEV/XDEV_ARCH evaluation if EMBEDDEDBUILD is set.
r269629:
In arm/release.sh, switch TARGET/TARGET_ARCH back to the
original XDEV/XDEV_ARCH make(1) variables.
In theory, this should have been a no-op, but the TARGET and
TARGET_ARCH are now unset in load_target_env() to avoid
collision with the chroot userland.
r269630:
Export variables in the arm/*.conf files because they
need to be passed through release.sh to arm/release.sh.
Set MK_TESTS=no for the xdev target.
r269635:
As part of the XDEV/XDEV_ARCH deprecation, the
'xdev-links' target was intentionally no longer
invoked automatically.
Invoke the xdev-links target after xdev, which
creates, for example, /usr/bin/armv6-freebsd-cc
symlink to /usr/armv6-freebsd/usr/bin/cc.
r269637:
Set TARGET and TARGET_ARCH to the XDEV and XDEV_ARCH
counterparts for the xdev and xdev-links make(1)
targets.

variables. These are intended to allow bypassing the
'svn co /usr/{src,doc,ports}' step in the chroot when the
tree exists from external means.
The use case here is that /usr/src, /usr/doc, and /usr/ports
in the chroot exist as result of zfs dataset clones, so it
is possible (and happens quite often) that the included
distributions may not be consistent. (This is not the case
for -RELEASE builds, but does happen for snapshot builds.)

When set to a non-empty value, the installation medium is
compressed with gzip(1) as part of the 'install' target in
the release/ directory.
With gzip(1) compression, downloadable image are reduced in
size quite significantly. Build test against head@263927
shows the following:
bootonly.iso: 64% smaller
disc1.iso: 44% smaller
memstick.img: 47% smaller
mini-memstick.img: 65% smaller
dvd1.iso: untested
This option is off by default, I would eventually like to
turn it on by default, and remove the '-k' flag to gzip(1)
so only compressed images are published on FTP.

After several months of testing and fixing (and breaking)
various parts of release/release.sh changes, it is now
possible to build FreeBSD/arm images as part of the release
process.
When EMBEDDEDBUILD is set in the release.conf file, release.sh
will create the build environment, then run a separate script
in release/${XDEV}/release.sh [1]. Currently, only arm is
supported.
The release/${XDEV}/release.sh configures the build environment
specific for the target image, such as installing gcc(1),
installing additional third-party software from the ports tree,
and fetching external sources.
Once the build environment is set up, release/${XDEV}/release.sh
runs Crochet, written by Tim Kientzle, which builds the userland
and kernel, and creates an image that can be written to an SD
card with dd(1). Many thanks to Tim for his work on Crochet.
Sample configurations for FreeBSD/arm boards are in the
release/arm/ directory, and Crochet configuration files for each
board are located in release/tools/arm/. Supported boards at this
time are: BEAGLEBONE, PANDABOARD, RPI-B, and WANDBOARD-QUAD.
Adding support for additional boards will continue in the
projects/release-embedded/ branch, and incrementally merged back
to head/.
Many thanks to the FreeBSD Foundation for the support and
sponsorship of this project.
[1] XDEV is used in order to keep the various configurations
organized by architecture, but since TARGET and TARGET_ARCH
are used to build the chroot, the values of those variables
cannot be used.

- Add a VCSCMD variable that defaults to 'svn checkout',
and update places 'svn co' is used directly.
- After sourcing a configuration file, prefix SRCBRANCH,
PORTBRANCH, and DOCBRANCH with the SVNROOT.
- Properly capitalize 'FreeBSD.org' in the default SVNROOT.
- Update Copyright.
release.conf.sample:
- Add an example to use git instead of svn, by nullifying
SVNROOT, and setting SRCBRANCH, DOCBRANCH, and PORTBRANCH
to the URL fo a git repository.
release.7:
- Document VCSCMD.

- Remove {SRC,DOC,PORT}REVISION variables, and use 'branch@rNNNNNN'
as the {SRC,DOC,PORT}BRANCH variables.
- Only set default KERNEL_FLAGS and WORLD_FLAGS make(1) jobs if the
number of CPUs is greater than 1.

the src/ tree into a directory that contains files/directories, such
as a case where a custom kernel configuration file is specified.
- Allow specification of multiple KERNCONFs to pass to 'make release'.
- Move evaluation of NODOCS/NOPORTS earlier, and set based on how the
release process expects these options to be evaluated.
- Wrap KERNCONF specification in double quotes, and use 'eval' so multiple
kernel configurations do not cause the build to fail in strange ways.
- Set WITHOUT_X11 for the port build flags for the documentation toolchain
build. Also run 'clean distclean' targets during port build.

the release/generate-release.sh script by nwhitehorn.
This script can use optional configuration file to override defaults,
making running multiple serialzied builds with different specific
configurations or architecture-specific tunings quite easy.
Sample overrideable options are included in the release.conf.sample
file.
