[coreboot] IBM x60t test - DSDT is in fact incomplete

[David Hubbard]

Hi Charles,

I'm focusing in on this error message first:

ACPI Warning: For \_SB_.PCI0.LPCB.EC__.LED_: Excess arguments - needs 1,
found 2

Can you take a look at the .asl files in your coreboot build? I believe you
will find something like "Method (LED, 2, NotSerialized)" which means the
LED method wants 2 arguments. Then look for calls to "LED ()" and if you
find one only passing 1 argument, that is the problem.

Looking at the decompiled vendor DSDT did not really reveal much in this
area, except that it is likely coreboot already has a "clean room"
re-implementation of the vendor DSDT since they both use a method called
"LED ()"
