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.

4a9932a436 mpc83xx: increase MONITOR_LEN to offset growing pains
Saving the environment leads to overwriting u-boot itself,
bricking boards.  Increase u-boot's image size so the environment
base address doesn't end up overlapping u-boot text.

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.

5b2793a3f3 mpc8323erdb: fix EEPROM page size and get MAC from EEPROM
This patch fixes eeprom page size so that you can now write more than
64 bytes at a time.

It also makes the board take MAC addresses, if found, from EEPROM.

User should place up to 4 addresses at offset 0x7f00, for
eth{,1,2,3}addr.  Any unused addresses should be zero.  This group of
four six-byte values should have it's CRC at the end.  crc32 and
eeprom commands can be used to accomplish this.

If CRC fails, MAC addresses come from the environment.  If CRC
succeeds, the environment is overwritten at startup.

5bbeea86eb mpc8323erdb: Improve the system performance
The following changes are based on kernel UCC ethernet performance:

1.  Make the CSB bus pipeline depth as 4, and enable the repeat mode
2.  Optimize transactions between QE and CSB.  Added CFG_SPCR_OPT
    switch to enable this setting.

The following changes are based on the App Note AN3369 and
verified to improve memory latency using LMbench:

3.  CS0_CONFIG[AP_n_EN] is changed from 1 to 0
4.  CS0_CONFIG[ODT_WR_CONFIG] set to 1.  Was a reserved setting
    previously.
5.  TIMING_CFG_1[WRREC] is changed from 3clks to 2clks  (based on
    Twr=15ns, and this was already the setting in DDR_MODE)
6.  TIMING_CFG_1[PRETOACT] is changed from 3clks to 2clks. (based on
    Trp=15ns)
7.  TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 6clks. (based on
    Tras=40ns)
8.  TIMING_CFG_1[ACTTORW] is changed from 3clks to 2clks. (based on
    Trcd=15ns)
9.  TIMING_CFG_1[REFREC] changed from 21 clks to 11clks.  (based on
    Trfc=75ns)
10. TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 7clks.  (based
    on Tfaw=50ns)
11. TIMING_CFG_2[ADD_LAT] and DDR_MODE[AL] changed from 0 to 1 (based
    on CL=3 and WL=2).

Remove the "#undef DEBUG" line from all Freescale 83xx board header files.
The inclusion of this line makes it impossible to enable debug code in
