cad5cef62a POWERPC: drivers: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

09cef8bd07 powerpc/85xx: Add lbc suspend support for PM
Power supply for LBC registers is off when system go to deep-sleep state.
We save the values of registers before suspend and restore to registers
after resume.

We removed the last two reservation arrays from struct fsl_lbc_regs for
allocating less memory and minimizing the memcpy size.

7145cf1209 powerpc/fsl-lbc: Fix for fsl_upm
If Freescale LBC driver fails to initialise itself from device tree, then
internal structure is freed only but not NULL-fied.  As result functions
fsl_lbc_find() after checking the structure is not NULL are trying to
access device registers.

4b16f8e2d6 powerpc: various straight conversions from module.h --> export.h
All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure.  We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.

d08e44570e powerpc/fsl_lbc: Add workaround for ELBC-A001 erratum
Simultaneous FCM and GPCM or UPM operation may erroneously trigger
bus monitor timeout.

Set the local bus monitor timeout value to the maximum by setting
LBCR[BMT] = 0 and LBCR[BMTPS] = 0xF.

0b824d2b10 P4080/mtd: Fix the freescale lbc issue with 36bit mode
When system uses 36bit physical address, res.start is 36bit
physical address. But the function of in_be32 returns 32bit
physical address. Then both of them compared each other is
wrong. So by converting the address of res.start into
the right format fixes this issue.

3ab8f2a2e7 P4080/eLBC: Make Freescale elbc interrupt common to elbc devices
Move Freescale elbc interrupt from nand driver to elbc driver.
Then all elbc devices can use the interrupt instead of ONLY nand.

For former nand driver, it had the two functions:

1. detecting nand flash partitions;
2. registering elbc interrupt.

Now, second function is removed to fsl_lbc.c.

b6e0e8c077 [MTD] [NAND] FSL-UPM: add multi chip support
This patch adds support for multi-chip NAND devices to the FSL-UPM
driver. This requires support for multiple GPIOs for the RNB pins.
The NAND chips are selected through address lines defined by the
FDT property "fsl,upm-addr-line-cs-offsets".

c0da99d5f7 powerpc: fix fsl_upm nand driver modular build
The fsl_upm nand driver fails to build because fsl_lbc_lock isn't
exported, the lock is needed by the inlined fsl_upm_run_pattern()
function:

ERROR: "fsl_lbc_lock" [drivers/mtd/nand/fsl_upm.ko] undefined!

Dave Jones purposed to export the lock, but it is better to just uninline
the fsl_upm_run_pattern().

When uninlined we also no longer need the exported fsl_lbc_regs, and
both fsl_lbc_lock and fsl_lbc_regs could be marked static.

While at it, also add some missing includes that we should have included
explicitly.

acaa7aa30a [POWERPC] fsl_lbc: implement few UPM routines
Freescale UPM can be used to adjust localbus timings or to generate
orbitrary, pre-programmed "patterns" on the external Localbus signals.
This patch implements few routines so drivers could work with UPMs in
safe and generic manner.

So far there is just one user of these routines: Freescale UPM NAND
driver.
