Re: AT91SAM9260-EK: Trying to load U-Boot env from NAND

Yes! I get it work, the problem was, that it had a problem to accept the
crc32-Checksum. So I just erased the sequence where this happens. Here the
patchfile:

[PATCH] resubmit: PPC440: Add flow control for serial port

Sorry for my mistake in my first submission..

This has been tested on our HCU5 PPC440EPx based board, where we
have only one serial port.

You mean you completely castrated all logic that would verify if the
environment is OK? Arrggghhhh...

> Maybe it isn't the best solution but it works ;)

You THINK it works, but actually it's completely broken.

Don't do that!!!

I object against applying such a patch.

Using hardware flow-control on the only available serial port (= con-
sole port) is fundamentally broken. It is not acceptable that a board
does not come up just because no  console  terminal  is  attached  or
because the console is in the wrong state.

This patch "only" enables the 4xx UART driver for hardware flow control
and doesn't configure it for the HCU5 board. So that should not be a
problem.

But this patch unfortunately has coding style issues:

> +#endif

Please use something like this:

if defined(CONFIG_CMD_HWFLOW) && defined(CONFIG_440) && \
   !defined(CONFIG_SERIAL_MULTI)
int hwflow_onoff(int flow_on)
{
	if (flow_on == 1) {
		/*
		 * The OUT2 bit may be written and read
		 * but it provides no function
		 */
		out8(UART_BASE + UART_MCR, 0x0b);
	} else {
		/* No modem control DTR RTS */
		out8(UART_BASE + UART_MCR, 0x00);
	}

	return 0;
}
#endif

   Which board are you using? Does it already have a boot loader on
the board? If does not, then you can use the tools from Freescale to
flash the boot loader image. These tools can be found at
