The editenv command can be used to edit an environment variable.
Editing an environment variable is useful when one wants to tweak an
existing variable, for example fix a typo or change the baudrate in the
'bootargs' environment variable.

Previously setenv() would only delete an environment variable if it
was passed a NULL string pointer as a value. It should also delete an
environment variable when it encounters a valid string pointer of
0-length.
This change/fix is generally useful and is necessary for the upcoming
"editenv" command.

If the 'buf' parameter is a non-0-length string, its contents will be
edited. Previously, the initial contents of 'buf' were ignored and the
user entered its contents from scratch.
This change is necessary to support the upcoming "editenv" command but
could also be used for future commands which require a user to modify
an existing string.

Previously, passing readline() or readline_into_buffer() a NULL 'prompt'
parameter would result in puts() printing garbage when
CONFIG_CMDLINE_EDITING was enabled.
Note that no board currently triggers this bug. Enabling
CONFIG_CMDLINE_EDITING on some boards (eg bab7xx) would result in
the bug appearing. This change is only intended to prevent someone
from running into this issue in the future.

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.
Fix this be adding a second mem_rsv into the size calculation. We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.

If "stdout" is not previously set, doing "setenv stdout lcd" had no
effect, since console redirection only worked if the environment
variable was already set; the second time you run setenv it worked.
Most default environments lack stdin/out/err definitions, so I'm sure
I'm not alone with this problem.
This patch simply moves a block of code out of a conditional, to do
the same work even if the variable was previously unset.

The basic memtest function tries to watch for ^C after each
pattern pass as an escape mechanism, but if things are horribly
wrong, we'll be stuck in an inner loop flooding the console with
error messages and never check for ^C. To make matters worse,
if the user waits for all the error messages to complete, we
then incorrectly report the test passed without errors.
Adding a check for ^C after any error is printed will give
the end user an escape mechanism from a console flood without
slowing down the overall test speed on a slow processor.
Also, the more extensive memtest quit after just a single error,
which is inconsistent with the normal memtest, and not useful if
if you are doing dynamic environmental impact testing, such as
heating/cooling etc.
Both tests now track the error count and report it properly
at test completion.

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.

These architectures don't need relocation fixups, so reduce their
codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS.
Also remove the reloc_off field from their global data structures
as it is no longer needed.
Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot. We will therefore increment XF_VERSION in the next commit,

Commit 4abd844d8e extended the fdt command parser to handle property
strings which are split across multiple arguments but it was broken for
byte streams and strings.
Byte stream parsing:
* Fixes where it would terminate early or go into an endless loop.
* Fixes a 0x00 being inserted into the data if there is a space after
'[' or a separate argument.
* Fixes dereferencing the argument pointer after the last argument.
* Checks for bad characters.
String parsing:
* Treat multiple arguments as a string list. This fixes an issue where
only the last argument was stored.

U-Boot can detect if an IDE device is present or not.
If not, and this new config option is activated, U-Boot
removes the ATA node from the DTS before booting Linux,
so the Linux IDE driver does not probe the device and
crash. This is needed for buggy hardware (uc101) where
no pull down resistor is connected to the signal IDE5V_DD7.

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:
- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines
Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.
