MPC8641D).

This is the basic board support for GE Fanuc's SBC310, a 3U single board
computer, based on Freescale's MPC8641D.

On booke processors, the code that maps low memory only uses up to three
CAM entries, even though there are sixteen and nothing else uses them.

Make this number configurable in the advanced options menu along with max
low memory size.  If one wants 1 GB of lowmem, then it's typically
necessary to have four CAM entries.

The code that maps kernel low memory would only use page sizes up to 256
MB.  On E500v2 pages up to 4 GB are supported.

However, a page must be aligned to a multiple of the page's size.  I.e.
256 MB pages must aligned to a 256 MB boundary.  This was enforced by a
requirement that the physical and virtual addresses of the start of lowmem
be aligned to 256 MB.  Clearly requiring 1GB or 4GB alignment to allow
pages of that size isn't acceptable.

To solve this, I simply have adjust_total_lowmem() take alignment into
account when it decides what size pages to use.  Give it PAGE_OFFSET =
0x7000_0000, PHYSICAL_START = 0x3000_0000, and 2GB of RAM, and it will map
pages like this:
PA 0x3000_0000 VA 0x7000_0000 Size 256 MB
PA 0x4000_0000 VA 0x8000_0000 Size 1 GB
PA 0x8000_0000 VA 0xC000_0000 Size 256 MB
PA 0x9000_0000 VA 0xD000_0000 Size 256 MB
PA 0xA000_0000 VA 0xE000_0000 Size 256 MB

Because the lowmem mapping code now takes alignment into account,
PHYSICAL_ALIGN can be lowered from 256 MB to 64 MB.  Even lower might be
possible.  The lowmem code will work down to 4 kB but it's possible some of
the boot code will fail before then.  Poor alignment will force small pages
to be used, which combined with the limited number of TLB1 pages available,
will result in very little memory getting mapped.  So alignments less than
64 MB probably aren't very useful anyway.

The code to map lowmem uses three CAM aka TLB[1] entries to cover it.  The
size of each is stored in three globals named __cam0, __cam1, and __cam2.
All the code that uses them is duplicated three times for each of the three
variables.

We have these things called arrays and loops....

Once converted to use an array, it will be easier to make the number of
CAMs configurable.

We currently have a few variants of fsl-booke processors (e500v1, e500v2,
e500mc, and e200).  They all have minor differences that we had previously
been handling via ifdefs.

To move towards having this support the following changes have been made:

* PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on
  e500mc or e200.  We use MMUCFG[NPIDS] to determine which case we are
  since we only touch PID1/2 in extremely early init code.

* Not all IVORs exist on all the processors so introduce cpu_setup
  functions for each variant to setup the proper IVORs that are either
  unique or exist but have some variations between the processors

This patch adds support for PCI-Express controllers as found on the
newer MPC83xx chips.

The work is loosely based on the Tony Li's patch[1], but unlike the
original patch, this patch implements sliding window for the Type 1
transactions using outbound window translations, so we don't have to
ioremap the whole PCI-E configuration space.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE.  Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE.  Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system.  Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.

Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should.  Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.

This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.

Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.

This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.
