no board configure it as 'n' and it's an issue to merge all defconfigs

On AT91SAM926x boards both types of NAND flash can be present
(8 and 16 bit data bus width).

mm_struct
Reorder mm_context_t to remove alignment padding on 64 bit
builds shrinking its size from 64 to 56 bytes.
This allows mm_struct to shrink from 840 to 832 bytes, so using
one fewer cache lines, and getting more objects per slab when
using slub.

Anomaly 05000480 on BF537 rev 0.0, 0.1, 0.2:
Multiple Simultaneous Urgent DMA Requests May Cause DMA System Instability
Suggested Workaround:
Program the DMA Traffic Control Period to a non-zero value. This forces
the DMA block to group accesses together rather than allow arbitration for
each piece of data placed on the internal DMA bus.

Since the bfin_write() func needs proper type information in order to
expand into the right bfin_writeX() variant, preserve the addr's type
when setting up the local __addr. Otherwise the helpers will detect
the variant based upon sizeof(void) which is almost never right.

SGI UV's uv_tlb.c driver has become rather hard to read, with overly large
functions, non-standard coding style and (way) too long variable, constant
and function names and non-obvious code flow sequences.
This patch improves the readability and maintainability of the driver
significantly, by doing the following strict code cleanups with no side
effects:
- Split long functions into shorter logical functions.
- Shortened some variable and structure member names.
- Added special functions for reads and writes of MMR regs with
very long names.
- Added the 'tunables' table to shortened tunables_write().
- Added the 'stat_description' table to shorten uv_ptc_proc_write().
- Pass fewer 'stat' arguments where it can be derived from the 'bcp'
argument.
- Function definitions consistent on one line, and inline in few (short) cases.
- Moved some small structures and an atomic inline function to the header file.
- Moved some local variables to the blocks where they are used.
- Updated the copyright date.
- Shortened uv_write_global_mmr64() etc. using some aliasing; no
line breaks. Renamed many uv_.. functions that are not exported.
- Aligned structure fields.
[ note that not all structures are aligned the same way though; I'd like
to keep the extensive commenting in some of them. ]
- Shortened some long structure names.
- Standard pass/fail exit from init_per_cpu()
- Vertical alignment for mass initializations.
- More separation between blocks of code.
Tested on a 16-processor Altix UV.

This patch adds support for a new version of the SGI UV hub
chip. The hub chip is the node controller that connects multiple
blades into a larger coherent SSI.
For the most part, UV2 is compatible with UV1. The majority of
the changes are in the addresses of MMRs and in a few cases, the
contents of MMRs. These changes are the result in changes in the
system topology such as node configuration, processor types,
maximum nodes, physical address sizes, etc.

Turns out the documentation is wrong and doing "RAISE 1" does not result
in a software reset, only a core reset. So when the on-chip rom has a
functioning reset helper, use it.

Since the value of these MMRs aren't changing, store the value in a local

implicitly forced by the volatile markings.

The BF537 SIC combines the gpio port H mask A interrupts with the
emac rx interrupt, so we need to demux this in software.
It also combines the gpio port H mask B and the emac tx interrupts,
and the watchdog and port F mask B interrupts, but since we don't
support mask B yet, just add the defines for now.

The search logic in the gpio demux walks all possible gpio blocks starting
at the specified pin. The trouble on bf537 parts when we demux the port
F and port G mask A interrupts is that we also demux port H mask A ints.
Most of the time this isn't an issue as people don't usually use port H,
but might as well avoid it when possible.

The SIC interrupt line muxing that the bf537 does is specific to this
CPU (thankfully), so rip it out of the common code and move it to a
bf537-specific file. This tidies up the common code significantly.

After some cache setup reordering changesets, the blackfin_cpudata init
was left behind. While cpu0's data was correct, cpu1's data was not.
Not that big of a deal as these are only used in the cpuinfo output, but
should still be fixed. So move the setup of these fields to the common
cache setup function to avoid this happening again in the future.

renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.
mackerel board has 2 USB ports.
But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.
We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.
