17f4cae4a5 Let us manage differences of Book-E PowerPC variations i.e. vendor /
implementation specific vs. the common architecture definition.

Bring PPC4XX defines (PSL, SPR, TLB). Note the new definitions under
BOOKE_PPC4XX are not used in the code yet.

This change set is not supposed to affect existing E500 support, it's just
another reorg step before bringing support for E500mc, E5500 and PPC465.

03479763b2 Import support for the Sony Playstation 3 using the OtherOS feature
available on firmwares 3.15 and earlier.

Caveats: Support for the internal SATA controller is currently missing,
as is support for framebuffer resolutions other than 720x480. These
deficiencies will be remedied soon.

Special thanks to Peter Grehan for providing the hardware that made this
port possible, and thanks to Geoff Levand of Sony Computer Entertainment
for advice on the LV1 hypervisor.

da89fa28c6 Add three new drivers for fan control and temperature reading on the
PowerMac7,2.

- The fcu driver lets us read and write the fan RPMs for all fans in the
  PowerMac7,2. This driver is PowerMac specific.
- The ds1775 is a driver to read the temperature for the drive bay sensor.
- The max6690 is another driver to read temperatures. Here it is used to
  read the inlet, the backside and the U3 heatsink temperature.

An additional driver, the ad7417, will follow later.

Thanks to nwhitehorn for guiding me through this driver development.

321578e3d0 Connect MPC85XX to the PowerPC build.
The kernel config file is KERNCONF=MPC85XX, so the usual procedure applies:

1. make buildworld TARGET_ARCH=powerpc
2. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

This default config uses kernel-level FPU emulation. For the soft-float world
approach:

1. make buildworld TARGET_ARCH=powerpc TARGET_CPUTYPE=e500
2. disable FPU_EMU option in sys/powerpc/conf/MPC85XX
3. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

de2fa7b8af Redefine bus_space_tag_t on PowerPC from a 32-bit integral to
a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.

The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.

With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.

5d8dd7e60b Rename OEA to AIM. The former means nothing as it applies to all
processors (it's the PowerPC Operating Environment Architecture).
AIM designates the processors made by the Apple-IBM-Motorola
alliance and those we typically support.

While here, remove the NetBSD option IPKDB. It's not an option
used by us. Also, PPC_HAVE_FPU is not used by us either. Remove
that too.

1ed3fed743 o Revert the part of if_gem.c rev. 1.35 which added a call to gem_stop()
to gem_attach() as the former access softc members not yet initialized
  at that time and gem_reset() actually is enough to stop the chip. [1]
o Revise the use of gem_bitwait(); add bus_barrier() calls before calling
  gem_bitwait() to ensure the respective bit has been written before we
  starting polling on it and poll for the right bits to change, f.e. even
  though we only reset RX we have to actually wait for both GEM_RESET_RX
  and GEM_RESET_TX to clear. Add some additional gem_bitwait() calls in
  places we've been missing them according to the GEM documentation.
  Along with this some excessive DELAYs, which probably only were added
  because of bugs in gem_bitwait() and its use in the first place, as
  well as as have of an gem_bitwait() reimplementation in gem_reset_tx()
  were removed.
o Add gem_reset_rxdma() and use it to deal with GEM_MAC_RX_OVERFLOW errors
  more gracefully as unlike gem_init_locked() it resets the RX DMA engine
  only, causing no link loss and the FIFOs not to be cleared. Also use it
  deal with GEM_INTR_RX_TAG_ERR errors, with previously were unhandled.
  This was based on information obtained from the Linux GEM and OpenSolaris
  ERI drivers.
o Turn on workarounds for silicon bugs in the Apple GMAC variants.
  This was based on information obtained from the Darwin GMAC and Linux GEM
  drivers.
o Turn on "infinite" (i.e. maximum 31 * 64 bytes in length) DMA bursts.
  This greatly improves especially RX performance.
o Optimize the RX path, this consists of:
  - kicking the receiver as soon as we've a spare descriptor in gem_rint()
    again instead of just once after all the ready ones have been handled;
  - kicking the receiver the right way, i.e. as outlined in the GEM
    documentation in batches of 4 and by pointing it to the descriptor
    after the last valid one;
  - calling gem_rint() before gem_tint() in gem_intr() as gem_tint() may
    take quite a while;
  - doubling the size of the RX ring to 256 descriptors.
  Overall the RX performance of a GEM in a 1GHz Sun Fire V210 was improved
  from ~100Mbit/s to ~850Mbit/s.
o In gem_add_rxbuf() don't assign the newly allocated mbuf to rxs_mbuf
  before calling bus_dmamap_load_mbuf_sg(), if bus_dmamap_load_mbuf_sg()
  fails we'll free the newly allocated mbuf, unable to recycle the
  previous one but a NULL pointer dereference instead.
o In gem_init_locked() honor the return value of gem_meminit().
o Simplify gem_ringsize() and dont' return garbage in the default case.
  Based on OpenBSD.
o Don't turn on MAC control, MIF and PCS interrupts unless GEM_DEBUG is
  defined as we don't need/use these interrupts for operation.
o In gem_start_locked() sync the DMA maps of the descriptor rings before
  every kick of the transmitter and not just once after enqueuing all
  packets as the NIC might instantly start transmitting after we kicked
  it the first time.
o Keep state of the link state and use it to enable or disable the MAC
  in gem_mii_statchg() accordingly as well as to return early from
  gem_start_locked() in case the link is down. [3]
o Initialize the maximum frame size to a sane value.
o In gem_mii_statchg() enable carrier extension if appropriate.
o Increment if_ierrors in case of an GEM_MAC_RX_OVERFLOW error and in
  gem_eint(). [3]
o Handle IFF_ALLMULTI correctly; don't set it if we've turned promiscuous
  group mode on and don't clear the flag if we've disabled promiscuous
  group mode (these were mostly NOPs though). [2]
o Let gem_eint() also report GEM_INTR_PERR errors.
o Move setting sc_variant from gem_pci_probe() to gem_pci_attach() as
  device probe methods are not supposed to touch the softc.
o Collapse sc_inited and sc_pci into bits for sc_flags.
o Add CTASSERTs ensuring that GEM_NRXDESC and GEM_NTXDESC are set to
  legal values.
o Correctly set up for 802.3x flow control, though #ifdef out the code
  that actually enables it as this needs more testing and mainly a proper
  framework to support it.
o Correct and add some conversions from hard-coded functions names to
  __func__ which were borked or forgotten in if_gem.c rev. 1.42.
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o In gem_pci_attach() in case attaching fails release the resources in
  the opposite order they were allocated.
o Make gem_reset() static to if_gem.c as it's not needed outside that
  module.
o Remove the GEM_GIGABIT flag and the associated code; GEM_GIGABIT was
  never set and the associated code was in the wrong place.
o Remove sc_mif_config; it was only used to cache the contents of the
  respective register within gem_attach().
o Remove the #ifdef'ed out NetBSD/OpenBSD code for establishing a suspend
  hook as it will never be used on FreeBSD.
o Also probe Apple Intrepid 2 GMAC and Apple Shasta GMAC, add support for
  Apple K2 GMAC. Based on OpenBSD.
o Add support for Sun GBE/P cards, or in other words actually add support
  for cards based on GEM to gem(4). This mainly consists of adding support
  for the TBI of these chips. Along with this the PHY selection code was
  rewritten to hardcode the PHY number for certain configurations as for
  example the PHY of the on-board ERI of Blade 1000 shows up twice causing
  no link as the second incarnation is isolated.
  These changes were ported from OpenBSD with some additional improvements
  and modulo some bugs.
o Add code to if_gem_pci.c allowing to read the MAC-address from the VPD on
  systems without Open Firmware.
  This is an improved version of my variant of the respective code in
  if_hme_pci.c
o Now that gem(4) is MI enable it for all archs.
