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.

c28d3bbe96 video: mb862xx: improve board-specific Lime configuration
To avoid board-specific code accessing the mb862xx registers directly,
the public function mb862xx_probe() has been introduced. Furthermore,
the "Change of Clock Frequency" and "Set Memory I/F Mode" registers
are now defined by CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx__MMR,
respectively. The BSPs for the socrates and lwmon5 boards have been
adapted accordingly.

dfcd7f2160 Redundant Environment: protect full sector size
Several boards used different ways to specify the size of the
protected area when enabling flash write protection for the sectors
holding the environment variables: some used CONFIG_ENV_SIZE and
CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even
a mix of both for the "normal" and the "redundant" areas.

Normally, this makes no difference at all. However, things are
different when you have to deal with boards that can come with
different types of flash chips, which may have different sector
sizes.

Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the
biggest sector size, which may include several sectors on boards using
the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE
or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the
case that only the first of these sectors get protected, while the
following ones aren't.

This is no real problem, but it can be confusing for the user -
especially on boards that use CONFIG_ENV_SECT_SIZE to protect the
"normal" areas, while using CONFIG_ENV_SIZE_REDUND for the
"redundant" area.

To avoid such inconsistencies, I changed all sucn boards that I found
to consistently use CONFIG_ENV_SECT_SIZE for protection. This should
not cause any functional changes to the code.

a5d212a263 mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

fb661ea444 85xx: socrates: autoprobe Lime chip
This patch is an attempt to implement autoprobing for the Lime
presence on the bus.
Configure GPCM for Lime CS2 and try to access chip ID registers.
Second read atempt delivers register values if the chip is present.

e64987a892 85xx: socrates: Enable Lime support.
This patch adds Lime GDC support together with support for the PWM
backlight control through the w83782d chip.  The reset pin of the
latter is attached to GPIO, so we need to reset it in
early_board_init_r.

3e79b588b5 85xx: Socrates: Major code update.
- Update the local bus ranges in the FDT for Linux for the various
  devices connected to the local bus via chip-select.

- Set the LCRR_DBYP bit in the LCRR for local bus frequencies
  lower than 66 MHz and uses I/O accessor functions consequently.

- UPM data update.

- Update of default environment and configuration.  Use I2C multibus
  as we do have two I2C buses.  Also enable sdram and ext2 commands.
