fd67077071 Make 32-bit PowerPC kernels, like 64-bit PowerPC kernels, position-independent
executables. The goal here, not yet accomplished, is to let the e500 kernel
run under QEMU by setting KERNBASE to something that fits in low memory and
then having the kernel relocate itself at runtime.

15fa652898 Build the powerpc64 kernel as a position-independent executable. At startup,
it processes its own ELF relocations and can be loaded and run in place at
any physical/virtual address.

NB: This requires an updated loader to boot!

fdc52c1fa0 Bump the version of config to the latest (3 year old, so upgrade
worries are long past). Also remove redundant MACHINE= declarations
and passing MACHINE/MACHINE_ARCH to module builds. That's now done in
common code.

fea385a6bf Not all Pmake derived makes quietly tolerate assignment from shell commands
with no output.  Add "echo" at the end these shell commands whose output is
assigned to a variable's value to ensure there is some output.

d90b849335 Add -Wa,-many to CFLAGS on PowerPC. This aids in building a kernel using
clang, which would otherwise complain about some 64-bit bridge mode

Kernel sources for 64-bit PowerPC, along with build-system changes to keep
32-bit kernels compiling (build system changes for 64-bit kernels are
coming later). Existing 32-bit PowerPC kernel configurations must be
updated after this change to specify their architecture.

6496d826cc Convert Freescale PowerPC platforms to FDT convention.
The following systems are affected:

  - MPC8555CDS
  - MPC8572DS

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Freescale MPC85XX 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).

  - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
    QUICC, UART, CFI.

  - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
    ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.

f6d4544853 Bump config(8) version and build requirement for config(8) to 600006. This
is caused by my latest changes to config(8). You're supposed to install new
config(8) in order to prevent yourself from seeing a warning about old
version of that tool.

You should configure the kernel with a new config(8) then.

3e0bd8923f We don't bump the config version for additions to config that aren't
used in the base system.  This has been much discussed in the past
(typically people giving me a hard time for it).  Since all that was
added to config was nocpu, and since we don't use it, we don't need to
bump the version.

64504c2ac7 Never hardcode /sys into these Makefiles. The proper way to spell it is $S.
Also, move the -I stuff to the centralized kern.pre.mk.  However, it
might be better to add these flags to files.conf.  This is a short
term fix to fix the broken builds on my machine (I don't have a valid
/sys link).

363d709ec6 The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers.  This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
    (all tw_cl* files), which is a consolidation of all OS-independent
    parts of the driver.  The FreeBSD OS specific portions of the
    driver go into an "OS Layer" (all tw_osl* files).
    This re-architecture is to achieve better maintainability, consistency
    of behavior across OS's, and better portability to new OS's (drivers
    for new OS's can be written by just adding an OS Layer that's specific
    to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
   include Online Capacity Expansion and multi-lun support, among others.
   More details about 3ware's 9.2 release can be found here:
   http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files.  For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.

1d9abdbe78 Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option.  This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device.  This broke things like the snd_emu10k1 device, which required
quotes to make it parse right.  The no-longer-needed quotes have been
removed from NOTES, GENERIC etc.  eg, I've removed the quotes from:
   device  snd_maestro
   device  "snd_maestro3"
   device  snd_mss

I believe everything will still compile and work after this.

a51c9b6627 Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

cf06489c2d Commit some infrastructure for turning on -Werror for kernel compiles.
It doesn't actually do it yet though.  This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on.  make -DNO_WERROR would also bypass all of it.

6242c9dd61 Factor the common parts of the Makefile.foo files. This introduces two
new files: kern.pre.mk, which contains most of the definitions, and
kern.post.mk, which contains most of the rules.

I've tested this on i386 and pc98.  I have had feedback on the sparc64
port, but no reports from anybody on alpha, ia64 or powerpc.  I
appologize in advance if I've broken you.
