5d9e9016ae Since for clang 3.5.0 ARM EHABI is now the default, the -mllvm
-arm-enable-ehabi flag is no longer supported.  Use it only for older
versions of clang.

6d4766c1b8 Remove MK_ARM_EABI, the armeb issues have been fixed. The code to support
the oabi is still in the tree, but it is expected this will be removed
as developers work on surrounding code.

With this commit the ARM EABI is the only supported supported ABI by
FreeBSD on ARMa 32-bit processors.

a297028904 Remove all traces of support for ARM chips prior to the arm9 series. We
never actually ran on these chips (other than using SA1 support in an
emulator to do the early porting to FreeBSD long long ago).  The clutter
and complexity of some of this code keeps getting in the way of other
maintenance, so it's time to go.

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang

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.

7498cee5f0 Fix LINT build for arm: NOTES defines LDFLAGS by way of a make option
but LDFLAGS is not (yet) passed on to the linker (via SYSTEM_LD et al).
Do so now. As such, any kernel configuration can now define linker
flags by setting LDFLAGS as normal and not have to revert to hacks
like setting DEBUG for flags that do not relate to debugging (see
sys/powerpc/conf/MPC85XX).

db5ef4fc77 Convert Marvell ARM platforms to FDT convention.
The following systems are involved:

  - DB-88F5182
  - DB-88F5281
  - DB-88F6281
  - DB-78100
  - SheevaPlug

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Marvell ARM SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
    good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

373bbe25ff Introduce basic support for Marvell families of system-on-chip ARM devices:
*  Orion
     - 88F5181
     - 88F5182
     - 88F5281

  * Kirkwood
     - 88F6281

  * Discovery
     - MV78100

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:

  * GPIO
  * Interrupt controller
  * L1, L2 cache
  * Timers, watchdog, RTC
  * TWSI (I2C)
  * UART

Other peripherals drivers will be introduced separately.
