66a4909a3d Blackfin: clean up trace buffer handling when crashing
Avoid banging on the trace MMRs when debugging is disabled, avoid calling
the funcs multiple times in a row, disable the trace buffer earlier in the
exception handler to avoid eating more user entries, and dump the buffer
before calling the kgdb hook.  This way we maximize useful debugging info
up front rather than needing external tools (like gdb/serial/etc...).

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) {
			...

4978e60584 ppc4xx: Cleanup Boot/FLASH TLB reassignment for PPC440/460
Background Info:
Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via
init.S) to speed up the boot process. In relocate_code (start.S) the
cache inhibit attribute for this TLB is set to disable cache. This is
needed for the CFI FLASH driver.

This patch now cleans this code up:
- CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not
  defined in the top of this file. This way, we can remove an ugly
  #ifdef in this code.
- Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..."
  statement with "#if defined(CONFIG_440)".
- Remove unnecessary cache invalidate calls resulting in faster bootup.
