So far VxWorks bootline can be contructed from various environment
variables, but when these variables do not exist we get these from
corresponding config macros. This is not helpful as it requires
rebuilding U-Boot, and to make sure these config macros take effect
we should not have these environment variables. This is a little
bit complex and confusing.
Now we change the logic to always contruct the bootline from
environments (the only single source), by adding two new variables
"bootdev" and "othbootargs", and adding some comments about network
related settings mentioning they are optional. The doc about the
bootline handling is also updated.

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

This patch clear and disable the data cache for vxWorks.
The entry point sysInit(int) intended by Windriver to be called from
the vxWorks bootrom, a very small vxWorks system.
The routine is called by the go() handler in the bootrom, that clears
the cache from start of image to end of usable memory.
The PowerPC implementations only invalidates and disable the cache,
the ARM implementations also flush it.
U-Boot will be on the safe side, if it disables the data cache before
calling vxWorks sysInit(int).

The current ELF loading function does a lot of work above and beyond a
simple "loading". It ignores the real load addresses and loads things
into their virtual (runtime) address. This is undesirable when we just
want it to load an ELF and let the ELF do the actual C runtime init.
So add a command line option to let people choose to load via either the
program or section headers. I'd prefer to have program header loading
be the default, but this would break historical behavior, so I'll leave
section header loading as the norm.

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 Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:

Change the bootelf setup function into a dedicated weak function called
do_bootelf_exec. This way ports can control the behavior however they
like before/after calling the ELF entry point.
It isn't generally save to execute applications outside of U-Boot with caches
enabled due to the way the Blackfin processor handles caches (requires
software assistance). This patch disables caches before booting an ELF or
just booting raw code. The previous discussion on the patch was that we
wanted to use weaks instead, but that proved to not be feasible when multiple
symbols are involved, which puts us back at the ifdef solution. I've
minimized the ugliness by moving the setup step outside of the main function.
