c7190f028f mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields
some LCRR bits are not documented throughout the 83xx family RMs.
New board porters copying similar board configurations might omit
setting e.g., DBYP since it was not documented in their SoC's RM.

Prevent them bricking their board by retaining power on reset values
in bit fields that the board porter doesn't explicitly configure
via CONFIG_SYS_<registername>_<bitfield> assignments in the board
config file.

also move LCRR assignment to cpu_init_r[am] to help ensure no
transactions are being executed via the local bus while CLKDIV is being
modified.

also start to use i/o accessors.

d9ac3d5a17 mpc83xx: set 64BIT_VSPRINTF for boards using nand_util
When enabling NAND support for a board, one must also define
CONFIG_SYS_64BIT_VSPRINTF because this is needed in nand_util.c
for correct output.

bdab39d358 rename CONFIG_CMD_ENV to CONFIG_CMD_SAVEENV
The CONFIG_CMD_ENV option controls enablement of the `saveenv` command
rather than a generic "env" command, or anything else related to the
environment.  So, let's make sure the define is named accordingly.

6c869637fe NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS
This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define

 #define NAND_MAX_CHIPS          CONFIG_SYS_MAX_NAND_DEVICE

but that's bogus and did not work anyhow.

2f2a5c3714 mpc83xx: Improve the performance of DDR memory
modify the CAS timings. my understanding is that these
settings decrease various wait times in the DDR interface.
Because these wait times are in clock cycles, and the DDR
clock on the 8315 RDB runs slower than on some other 83xx
platforms, we can dial down these values without a problem,
thereby decreasing the latency of memory a little.

25f5f0d49a 83xx: mpc8315erdb: add support for switching between ULPI/UTMI USB PHYs
Freescale ships MPC8315E-RDB boards either with TSEC1 and USB UTMI
support, or without TSEC1 but with USB ULPI PHY support in addition.
With this patch user can specify desired USB PHY.

Also, it seems that we can't distinguish the two boards in software, so
user have to set `mpc8315erdb' environment variable to either 'tsec1'
(TSEC1 enabled) or `ulpi' (board with ULPI PHY, TSEC1 disabled), so that
Linux will not probe for TSEC1.

f9023afbdf 83xx/85xx: further localbus cleanups
move the BRx_* and ORx_* left behind in mpc85xx.h 

The same is needed for mpc8xx.h and mpc8260.h (defines are almost
the same, just few differences which needs some attention though).

But the bad news for mpc8xx and mpc8260 is that there are a lot of users
of these defines. So this cleanup I'll leave for the "better times".
