This patch adds the Kconfig and Makefile for the new S5P6440 machine
and platform directories. It also updates arch/arm Kconfig and Makefiles
to include the support for the new S5P6440 CPU.

The name of this entry is badly chosen, as 6440 only has groups 1, 2,
5, 6, and 8. What about IRQ_EINT_GROUPS? Or anything that would
represent the actual function...

Group 8 has interrupts numbered from 3 to 11, so this should read 12.

I'm still wondering about setting the clocks here. While the code looks
perfectly correct, it means that every single 6440 based platform has
to provide this setup. Not fun, and error prone. I believe that
platform support code should provide some sane defaults.

I suggest you implement some kind of default configuration in
arch/arm/plat-s5p/s5p6440-init.c (following code is untested):

static struct s3c24xx_uart_clksrc s5p6440_serial_clocks[] = {
	[0] = {
		.name		= "pclk_low",
		.divisor	= 1,
		.min_baud	= 0,
		.max_baud	= 0,
	},
	[1] = {
		.name		= "uclk1",
		.divisor	= 1,
		.min_baud	= 0,
		.max_baud	= 0,
	},
};

/* uart registration process */
void __init s5p6440_common_init_uarts(struct s3c2410_uartcfg *cfg, 
				      int no)
{
	int i;

	for (i = 0; i < no; i++)
		if (!cfg[i]->clocks) {
			cfg[i]->clocks = s5p6440_serial_clocks;
			cfg[i]->clocks_size = ARRAY_SIZE(s5p6440_serial_clocks);
		}

	s3c24xx_init_uartdevs("s3c6400-uart", s5p_uart_resources,
			      cfg, no); 
}

This way, most of the configurations which are using the default
get it for free, and a configuration can always specify its particular
requirements.

Yeah, your suggestion is some reason. Let me check about that. Thanks.

According to the UM's '5.10 PORT P Control Registers', it has 11 interrupts
numbered from 3 to 10. So I think it's right.

Oh, you're right. I'm sorry for my mistake. Only one under bar is right, not
two. I'll change it.

Ah, it looks like a documentation bug, then... My UM describes
EINT8[8:11]. Probably yours is more correct.

Fast. Cheap. Reliable. Pick two.

Marc,

Anyway, I will check another our UM.
My UM version is Rev0.10_090728.

Thanks.
