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.Signed-off-by: Jiang Yutang

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.Signed-off-by: Alexandre Rusev

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.Signed-off-by: Paul Gortmaker

They are getting it through device.h --> module.h path, but we want

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.Signed-off-by: Shengzhou Liu

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.Signed-off-by: Lan Chunhe-B25806

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.

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".Signed-off-by: Wolfgang Grandegger

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.Reported-by: Dave Jones

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.Signed-off-by: Anton Vorontsov
