'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

Fix:
cmd_fdc.c: In function 'fdc_read_data':
cmd_fdc.c:435:6: warning: variable 'flags' set but not used
[-Wunused-but-set-variable]
cmd_fdc.c:432:16: warning: variable 'pcn' set but not used
[-Wunused-but-set-variable]
cmd_fdc.c:431:20: warning: variable 'lastblk' set but not used
[-Wunused-but-set-variable]

Note: no attempts were made to otherwise cleanup the code.

Rather than having a bunch of random commands handle autostart behavior,
unify the logic in a single place.  This also fixes building of these

different commands when bootm is disabled.

This reverts commit 5a442c0addc69d0c4b58e98e5aec1cf07576debb.

This commit changed the behaviour of getenv_yesno() (both the default
behaviour and the documented behaviour for abbreviated arguments)
which resulted in problems in several areas.

Use the new helper func to clean up duplicate logic handling of the
autostart env var.

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and they're pretty much all outdated (wrt constness).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.

Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.

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) {
			...

The AmigaOneG3SE board has been orphaned or a very long time, and
broken for more than 12 releases resp. more than 3 years.  As nobody
seems to be interested any more in this stuff we may as well ged rid
of it, especially as it clutters many areas of the code so it is a
continuous pain for all kinds of ongoing work.
