their growth by adjusting default load and fdt addresses.

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.

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.

bootdelay set to -1 'permanently' disables autobooting, even if
bootcmd is specified. Change to a positive value to allow
autobooting when a bootcmd is set.

Change all code that conditionally operates on high bat
registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS
instead of the myriad ways this is done now. Define the option
for every config for which high bats are supported (and
enabled by early boot, on parts where they're not always
enabled)

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.

Commit 55774b512f broke the onboard USB

This fixes it by defining CONFIG_PCI_SKIP_HOST_BRIDGE in the board's

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
other source files, because "#define DEBUG" typically needs to be defined
before any header files are included.
