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) {
			...

This patch adds support for the T3CORP board, based on the
AppliedMicro (APM) PPC460GT.
Signed-off-by: NStefan Roese <sr@denx.de>

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.

This patch makes it possible to overwrite the default auto-calibration
scan window (SDRAM_WRDTR.[WDTR], SDRAM_CLKTR.[CKTR] values) with

This patch adds redundant environment for environment in SPI flash.
I took env_flash.c as an example and slightly modified it. Apart
from adapting things to SF, I also slightly changed the decision
logic to use area 2 as a default in case the flags are wrong because
not having a default path worried me.

I did not add a section for CONFIG_ENV_IS_IN_SPI_FLASH in environment.h
because I did not understand if this is desired and/or needed.
So to use the feature, one has to set CONFIG_ENV_OFFSET_REDUND _and_
CONFIG_SYS_REDUNDAND_ENVIRONMENT.

I checked it by powering off my board several times during flash
erase or write, because I do not know if there are other stress
test scenarios.

ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI
specification suggests) which leads to the controller seeing the "token" field
as the previous call has left it, i.e.:
- if a timeout occured on the previous call (Active bit left as 1), controller
  incorrectly tries to complete a previous transaction on a newly programmed
  endpoint;
- if a halt occured on the previous call (Halted bit set to 1), controller just
  ignores the newly programmed TD(s) and the function then keeps returning error
  ad infinitum.

This turned out to be caused by the wrong orger of the arguments to the memset()
call in ehci_alloc(), so the allocated TDs weren't cleared either.

While at it, stop needlessly initializing the alternate next TD pointer in the
QH transfer overlay...
