Modifications to support console multiplexing. This is controlled using
CONFIG_SYS_CONSOLE_MUX in the board configuration file.
This allows a user to specify multiple console devices in the environment
with a command like this: setenv stdin serial,nc. As a result, the user can
enter text on both the serial and netconsole interfaces.
All devices - stdin, stdout and stderr - can be set in this manner.
1) common/iomux.c and include/iomux.h contain the environment setting
implementation.
2) doc/README.iomux contains a somewhat more detailed description.
3) The implementation in (1) is called from common/cmd_nvedit.c to
handle setenv and from common/console.c to handle initialization of
input/output devices at boot time.
4) common/console.c also contains the code needed to poll multiple console
devices for input and send output to all devices registered for output.
5) include/common.h includes iomux.h and common/Makefile generates iomux.o
when CONFIG_SYS_CONSOLE_MUX is set.

My text-editor (vim) has a bit of trouble syntax-highlighting the
cmd_nvedit.c file, because it apparently does not parse C
ifdef/else/endif. The following patch does not change the behavior of
the code at all, but does allow the editor to properly
syntax-highlight the file.

This is pretty incomplete...it doesn't handle reading the environment
before relocation, it doesn't support redundant environment, and it
doesn't support embedded environment. But apart from that, it does
seem to work.

Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA
Changes:
- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
DV_EVM. Can't check if it works on SONATA, don't have a board any more,
but it at least compiles.
Here is an excerpt from session log on SCHMOOGIE...

Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

update setenv() function so that entering a NULL value for the
variable's value will delete the environmental variable

Acked-by: Stefan Roese <sr@denx.de>
Make sure the string passed as variable name does not contain a '='
character. This not only prevents the common error or typing
"setenv foo=bar" instead of "setenv foo bar", but (more importantly)
also closes a backdoor which allowed to delete write-protected
environment variables, for example by using "setenv ethaddr=".
- Added support for both 8 and 16 bit mode access to System ACE CF
through MPU.
- Fixed missing System ACE CF device during get FAT partition info
in fat_register_device function.
- Enabled System ACE CF support on ML300.
* Patch by Sean Chang, 09 Aug 2004:
Synch defines for saveenv and do_saveenv functions so they get
compiled under the same statement.
* Patch by Sascha Hauer, 28 Jun:
- add generic support for Motorola i.MX architecture
- add support for mx1ads, mx1fs2 and scb9328 boards
* Patches by Marc Leeman, 23 Jul 2004:
- Add define for the PCI/Memory Buffer Configuration Register
- corrected comments in cpu/mpc824x/cpu_init.c
* Add support for multiple serial interfaces
(for example to allow modem dial-in / dial-out)
update for for Atmel AT91RM9200DK development kit:
- support for environment variables in DataFlash
- Atmel DataFlash AT45DB1282 support
* Patch by Jeff Carr, 11 Nov 2003:
add support for new version of 8270 processors
* Patches by George G. Davis, 05 Nov 2003:
- only pass the ARM linux initrd tag to the kernel when an initrd
is actually present
- update omap1510inn configuration file
- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
when watchdog is on
* Update baudrate in bd_info when it gets changed
* Add watchdog trigger points while waiting for serial port
(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)
Add code for AmigaOne board
(preliminary merge to U-Boot, still WIP)
* Patch by Jon Diekema, 12 Nov 2002:
- Adding URL for IEEE OUI lookup
- Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
being defined.
- In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
root-on-nfs macros are designed to switch how the default boot
method gets defined.
