Split the display command into generic interface and hardware-specific
realization for PDSP188x LED display found on hmi1001 and manroland
boards. Simple interface for LED displays is defined in
include/led-display.h and described in doc/README.LED_display.
Driver-specific implementation was moved into drivers/misc/pdsp188x.c
file (enabled with CONFIG_PDSP188x set).Signed-off-by: Ilya Yanok

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {

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 ThermostatUsage:
dtt - Read temperature from digital thermometer and thermostat.After:
=> help dtt
dtt - Read temperature from Digital Thermometer and ThermostatUsage:
dttSigned-off-by: Wolfgang Denk

Remove command name from all command "usage" fields and update
common/command.c to display "name - usage" instead of
just "usage". Also remove newlines from command usage fields.Signed-off-by: Peter Tyser

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.Signed-off-by: Jon Loeliger

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)Signed-off-by: Jon Loeliger
