Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

In case of incorrect command invocations U-Boot used to print pretty
useless "usage" messages, for example:
=> nand markbad
Usage:
nand - NAND sub-system
In the result, the user would have to run the "help" command to get
the (available) information about correct command usage. Change this,
so that this information gets always printed.
Note that this changes the user interface of all commands, but
hopefully to the better.

The printing code would check the same environment byte multiple times and
write to the console one byte at a time. For some devices (such as the
Blackfin JTAG console which operates in 8 bytes at a time), this is pretty
damned slow. So create a small 16 byte buffer to fill up and send to puts
as needed. In the process, unify the different print functions, shrink
the resulting code (source and compiled), and avoid excess env reads as
those too can be somewhat expensive depending on the board.

The static function compare_sign is only used to compare the fs_type string
and does not do anything more than what strncmp does.
The addition of the trailing '\0' to fs_type, while legal, is not needed
because the it is never printed out and strncmp does not depend on NULL
terminated strings.

There is actually no good reason to enforce that all board
configuations must define default settings for "mtdids" and
"mtdparts". Actually this may be difficult to handle, especially on
boards where different sizes of flash chips can be fit, so there is no
real "default" partition map for all boards.
Lift this arbitrary limitation.

This patch removes all references to the direct CFI FLASH interface
(via flash_info[]). Now that all FLASH types currently handled in
mtdparts are available (if selected, see below) via the MTD infrastructure.
This is NOR, NAND and OneNAND right now. This can be achieved by defining
the following options:
CONFIG_MTD_DEVICE (for all FLASH types)
plus
CONFIG_FLASH_CFI_MTD (for NOR FLASH)
So we need to add those defines to the board config headers currently
using the mtdparts commands. This is done via another patch, so
we shouldn't break mtdparts compatibility.
One big advantage from this solution is that the cmd_mtdparts.c is
*much* cleaner now. Lot's of #ifdef's are removed and the code itself
is smaller. Additionally the newly added MDT concatenation feature
can new be used via the mtdparts infrastructure and therefor via
UBI etc.

This new define enables mtdcore.c compilation and with this we can
select the MTD device infrastructure needed for the reworked mtdparts
command.
We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and
CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above)
for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

By changing the cmd_mtdparts to only use the MTD infrastructure and
not the direct interface to the CFI NOR FLASH driver we now need
to add the MTD infrastructure to all boards using those mtdparts
commands. This patch adds those components:
CONFIG_MTD_DEVICE (for all FLASH types)
plus
CONFIG_FLASH_CFI_MTD (for NOR FLASH)
To all board maintainers: Please test this on your platforms and
report any problems/issues found. Thanks.

This patch adds concatenation support to the U-Boot MTD infrastructure.
By enabling CONFIG_MTD_CONCAT this MTD CFI wrapper will concatenate
all found NOR devices into one single MTD device. This can be used by
e.g by UBI to access a partition that spans over multiple NOR chips.

There are currently 3 versions of the zoom2 board.
The production board, that is currently being released.
The beta board, similar in form to the production board but not released.
The alpha board, a set of PCBs with a very limited circulation.
GPIO 94 is used to determine the version of the board. If GPIO 94 is clear,
the board is a production board, otherwise it is a beta board.
The alpha board will likely be mistaken for a beta board. An alpha board

Initial U-Boot support for the DaVinci DM355 EVM. This is a board
from Spectrum Digital. Board docs include schematic and firmware
for its microcontroller:
http://c6000.spectrumdigital.com/evmdm355/revd/
Most of the DM355 chip is fully documented by TI, the most notable
exception being the MPEG/JPEG coprocessor (programmable using codecs
available at no cost from TI), which is omitted from its DM335 sibling:
http://focus.ti.com/docs/prod/folders/print/tms320dm355.html
This version can boot from the on-board DM9000 Ethernet chip, after
being loaded (from NAND, MMC/SD, or UART). In the near future, NAND
and USB support could be added ... NAND support is being held back
until the support for the 4-bit ECC hardware is ready.
