f51cdaf191 83xx/85xx/86xx: LBC register cleanup
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers.  Merge
this into a single spot.

To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.

In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.

I have done a successful ppc build all and tested a board or two from
each processor family.

33846df28f Add wait flags to support board/chip specific delays
The NAND flash on the TQM8548_BE modules requires a short delay after
running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE
requires a further short delay after writing out a buffer. Normally the
R/B pin should be checked, but it's not connected on the TQM8548_BE.
The corresponding Linux FSL UPM driver uses similar delay points at the
same locations. To manage these extra delays in a more general way, I
introduced the "wait_flags" field allowing the board-specific driver to
specify various types of extra delay.

e93c1c169d Add multi chip support to the FSL-UPM driver
This patch adds support for multi-chip NAND devices to the FSL-UPM
driver. The "dev_ready" callback of the "struct fsl_upm_nand" is now
called with the argument "chip_nr" to allow testing the proper chip
select line. The NAND support of the MPC8360ERDK is updated as well.
No other boards are currently using the FSL UPM driver.

b4fe1a7109 MPC8360ERDK: adapt NAND interface for the re-written FSL NAND UPM driver
This patch is based on the following patch sent a few minutes ago:
"NAND FSL UPM: driver re-write using the hwcontrol callback"
It is untested, of course. Anton, could you please give it a try.
