be51c5c98b board/esd/cpci750/cpci750.c: Fix error handling
ThE code recorded error conditions but did not pass these on to the
higher level caller.  Fixing this fixes also this build warning:
cpci750.c: In function 'do_loadpci':
cpci750.c:569:6: warning: variable 'status' set but not used
[-Wunused-but-set-variable]

36ebb78779 do_bootm: unify duplicate prototypes
The duplication of the do_bootm prototype has gotten out of hand,
and they're pretty much all outdated (wrt constness).  Unify them
all in command.h.

54841ab50c Make sure that argv[] argument pointers are not modified.
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) {
			...

a89c33db96 General help message cleanup
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

fcd69a1a57 Clean up usage of icache_disable/dcache_disable
There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache.  All callers of invalidate_l1_instruction_cache()
call icache_disable() right after.  Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.

Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().
