[coreboot] rtc wake up does not work on ASUS M2V-MX SE

[Fengwei Zhang]

Hi Rudolf,

Thanks for your email. I tried with your way, but the RTC0 device still 
is not visible.
either from /dev/ or /sys/class/ directory.

I also extract DSDT table from Original BIOS,

	Device(RTC0)
	{
	Name(_HID, EISAID("PNP0B00"))
	Name(CRS0, ResourceTemplate()
	{
	IO(Decode16, 0x0070, 0x0070, 0x00, 0x02)
	IRQNoFlags() {8}
	})
	Name(CRS1, ResourceTemplate()
	{
	IO(Decode16, 0x0070, 0x0070, 0x00, 0x02)
	})
	Method(_CRS, 0, NotSerialized)
	{
	If(LOr(LEqual(SHTB, Zero), LEqual(^^HPET.SHTS(), Zero)))
	{
	Return(CRS0)
	}
	Return(CRS1)
	}
	}
It looks like same thing you posted in last email. but I cannot compile 
successfully for this one because of some unrecognized symbol of this 
line: LEqual(^^HPET.SHTS(),

I did enable the power button in lpc.c file.

Is there anything else I am missing?

Thanks,
Fengwei
