c81b12e0d7 Revert r336773: it removed too much.
r336773 removed all things xscale. However, some things xscale are
really armv5. Revert that entirely. A more modest removal will follow.

626930c2fd Remove xscale support
The OLD XSCALE stuff hasn't been useful in a while. The original
committer (cognet@) was the only one that had boards for it. He's
blessed this removal. Newer XSCALE (GUMSTIX) is for hardware that's
quite old. After discussion on arm@, it was clear there was no support
for keeping it.

The elf trampoline was never been supported for ARMv6 and ARMv7 and was

78a25cc760 Partially revert r336353: sys/conf/* %VERSREQ bumps
The changes made in r335998 don't strictly require a newer config(8),
though it is advised. The %VERSREQ bumps were premature.

2df45ae0d0 config(8): Bump major version after r335998
config-generated hints.c/env.c from r335998 and later are incompatible with
earlier kernels due to no longer setting envmode/hintmode. A minor bump for
this is insufficient, as matching major version with a later minor version
is still viewed as backwards-compatible.

This was an MI kernel change, soo all VERSREQ's are bumped.

25bc561e68 There's two files in the sys tree named inflate.c, in addition
to it being a common name elsewhere. Rename the old kzip one
to subr_inflate.c.

This actually fixes the build issues on sparc64 that my inclusion of
.PATH ${SYSDIR}/kern created in r336244, so also revert the broken
workaround I committed in r336249.

This slipped passed me because apparently, I never did a clean build.

2d09b07279 Make kernel option KERNVIRTADDR optional, remove it from std.<platform>
files that can use the default value.

It used to be required that the low-order bits of KERNVIRTADDR matched
the low-order bits of the physical load address for all arm platforms.
That hasn't been a requirement for armv6 platforms since FreeBSD 10.
There is no longer any relationship between load addr and KERNVIRTADDR
except that both must be aligned to a 2 MiB boundary.

This change makes the default KERNVIRTADDR value 0xc0000000, and removes the
options from all the platforms that can use the default value.  The default
is now defined in vmparam.h, and that file is now included in a few new
places that reference KERNVIRTADDR, since it may not come in via the
forced-include of opt_global.h on the compile command line.

0b972ac92e Support armv7 builds for userland
Make armv7 as a new MACHINE_ARCH.

Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.

Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).

Add armv7 to the universe build.

dc653882d4 Always pass the linker emulation via -m when linking modules and kernels.
Previously the linker emulation was only passed when building binary
objects for firmware modules.  This change always passes the desired
output format for kernel modules and kernels rather than requiring the
toolchain's default output format to match the desired output format.
This in turn permits use of external toolchains whose default output
format does not match the desired output format.

cc787e3d0e Change md(4) to use weak symbols as start, end and size for the embedded
root disk. The embedded image is linked into the kernel in the .mfs
section.

Add rules and variables to kern.pre.mk and kern.post.mk that handle the
linking of the image. First objcopy is used to generate an object file.
Then, the object file is linked into the kernel.

46e95f646c 2 years, 10 months, 22 days after the projects/arm_eabi branch was created
make the ARM EABI the default ABI on arm, armeb, armv6 and armv6eb.

This is intended to be the default ABI from now on with the old ABI to be
retired. Because of this all users are strongly suggested to upgrade to the
ARM EABI.

As the two ABIs are incompatible it is unlikely upgrading in place will
work. Users should perform a full backup and either use an external machine
to upgrade, or install to an alternative location on their media. They
should also reinstall all ports or packages when these are available.

The only known issues are:
 - pkg incorrectly detects the ABI. This is fixed upstream, and will a
   patch will be made to the port.
 - GDB can have issues with executables built with clang.

__FreeBSD_version has been bumped.
