This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.
armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
* WITH_ARM_EABI
* WITHOUT_GCC
* WITHOUT_GNUCXX
In addition, without an external toolchain, the following need to be left
as their default:
* WITH_CLANG
* WITH_CLANG_IS_CC
As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.
broken. None of our kernels can boot armv6eb. The little-endian kernels do

make before starting the universe targets themselves. Otherwise, all of
the targets would attempt to build make simultaneously, overwriting each
other's copies of the make object files and executable. This could lead
to strange errors, for example when partially-written make executables
are invoked.
Also amend r216620, to make the rest of universe wait properly until the
upgrade_checks target is finished, by adding universe_${target}_prologue
to the .ORDER target. Otherwise, make will be too smart for its own
good, and start building the universe targets simultaneously with the
prologues anyway.

starting the kernels. Before this the kernels would be built as part of the
last architecture universe target. There can cause problems when this world
finishes before the other worlds as the host compiler may be picked up
rather than the target compiler.
The solution is to add a target to build the universe kernels that depends
on all the world targets finishing. As we may not be building a world only
depend on it when MAKE_JUST_KERNELS is undefined.
The automation can set TARGET_ARCH and TARGET and then make various
top-level targets, including buildLINT and buildkernel (with
KERNCONF=LINT). Previously there was no way to generate the LINT
kernel configuration without having to do something exceptionally
painful.
1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to
halting when sub-commands fail. Add "set -e" to compound commands so
that bmake is informed when sub-commands fail.
6. Make sure crunchgen uses the same make as the rest of the build. This
is important when the make utility isn't called make (but bmake for
example).
7. While here, add support for using MAKEOBJDIR to set the object tree
location. It's the second alternative bmake looks for when determining
the actual object directory (= .OBJDIR).

r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb
This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.
This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

When "make update" is run using a tree's makefile, it can also use
"cvs" (except for www/) and "svn" (only src/).
Clean up documentation and code regarding "make update":
- Increase oddness by adding support for WWWSUPFILE and NO_WWWUPDATE to
Makefile.inc1 (analogous to PORTSSUPFILE/NO_PORTSUPDATE and
DOCSUPFILE/NO_DOCUPDATE; WWWSUPFILE already supported by www/Makefile).
- Document all trees that support CVS_UPDATE.
- Document all trees that support SUP_UPDATE.
- Document SVN_UPDATE.
- Document NO_WWWUPDATE.
- make.conf(5) mistakenly said that *SUPFILE* had defaults.
- Add an example entry for WWWSUPFILE.
Some files keep the SUN4V tags as a code reference, for the future,
if any rewamped sun4v support wants to be added again.
