Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.
If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

!!!fix comment in callback
CONFIG_ENV_VARS_UBOOT_CONFIG creates environment variables indicating
which configuration U-Boot was built for. Some U-Boot binaries run on
multiple boards, and hence this information may not uniquley describe
the HW that U-Boot is actually running on. Another patch introduces
environment variable board_name to represent that. In order to avoid
scripts having to check $board_name, use it if set, and then fall back
to using $board, make CONFIG_ENV_VARS_UBOOT_CONFIG also set a default
value for board_name, so that variable is always available.

This can be useful for generic scripts. For example, rather than hard-
coding a script to ext2load tegra-harmony.dtb, it could load
${soc}-${board}.dtb and hence not need adjustments to run on multiple
boards.

Cleanup the env_embedded.c checkpatch warnings, errors and coding style.
There is one error left though:
ERROR: Macros with multiple statements should be enclosed in a do - while loop
#79: FILE: u-boot/common/env_embedded.c:79:
+#define GEN_ABS(name, value) \
+ asm(".globl " GEN_SYMNAME(name)); \
+ GEN_SET_VALUE(name, value)
total: 1 errors, 0 warnings, 213 lines checked
We cannot enclose that statement in a do - while loop,
because these are a global assembly declarations.

For people who want to manually extract the embedded environment so that
it can be manually packed into the final u-boot image, add a config opt
to force building of the envcrc tool.

The env code is protected by the ENV_IS_EMBEDDED define, so attempting to
compile the code when this isn't defined is pointless. Now that the env
headers have unified around CONFIG_ENV_IS_EMBEDDED, convert the build
system to only build the env objects when this is enabled. And now that
the env code is conditionally compiled, we can drop the source code checks.
For people who want to extract the environment manually, add a new option
CONFIG_BUILD_ENVCRC that only enables the envcrc utility.

Added as a convenience for other platforms that uses MPC8360 (has 8 UCC).
Six eth interface is chosen because the platform I am using combines
UCC1&2 and UCC3&4 as 1000 Eth and the other four UCCs as 10/100 Eth.

With recent toolchains, the environment sectors were no longer aligned to
sector boundaries. The reason was a combination of two bugs:
1) common/environment.c assumed that CONFIG_TQM8xxL would be defined
for all TQM8xxL and TQM8xxM boards. But "include/common.h", where
this gets defined, is not included here (and cannot be included
without causing lots of problems).
Added a new #define CFG_USE_PPCENV for all boards which really
want to put the environment is a ".ppcenv" section.
2) The linker scripts just include environment.o, silently assuming
that the objects in that file are really in the order in which
they are coded in the C file, i. e. "environment" first, then
"redundand_environment", and "env_size" last. However, current
toolchains (GCC-4.x) reorder the objects, causing the environment
data not to start on a flash sector boundary:
Instead of: we got:
40008000 T environment 40008000 T env_size
4000c000 T redundand_environment 40008004 T redundand_environment
40010000 T env_size 4000c004 T environment
Note: this patch fixes just the first part, and cures the alignment
problem by making sure that "env_size" gets placed correctly. However,
we still have a potential issue because primary and redundant
environment sectors are actually swapped, i. e. we have now:
40008000 T redundand_environment
4000c000 T environment
40010000 T env_size
This shall be fixed in the next version.

pre-define a MAC address; use CONFIG_HAS_ETH* to enable support for
additional ethernet addresses.
* Cleanup drivers/i82365.c - avoid duplication of code
* Fix bogus "cannot span across banks" flash error message
* Add support for CompactFlash for the CPC45 Board.
- Add port to MPC555/556 microcontrollers
- Add support for cmi customer board with
Intel 28F128J3A, 28F320J3A or 28F640J3A flash.
* Patch by Rick Bronson, 28 Mar 2003:

(so far only 8xx -- needed on LWMON with 100ms watchdog)
* Improve command line tool to access the U-Boot's environment
(figuration of the utility, using a config file)
