About coreboot table , where is its location in memory ? Its size ? 
Its contents ? Is it saved in buffer ?




The coreboot table typically lives at the end of physical memory in the 
4G space (e.g. in "cbmem space"). There is a
forwarder entry pointing to it, living in the lower 4k of memory 
(typically at 0x500)


The coreboot table contains various information coreboot collects about 
the system, such as

- memory map
- coreboot version
- cmos options
- framebuffer configuration

You can use the nvramtool utility to dump the coreboot table and look at it.

 Ah, duh, your right. But what could be causing this then?

 Kernel:
 PCI quirk: region 0400-047f claimed by ICH4 ACPI/GPIO/TCO

 Can't say without more kernel message context.

Well that the PNP subsytem needs to be aware on non-std bars which claim this
IO. Imagine if PCI IO allocator in linux will for some non-assigned resource
assign same region as above. Well this wont happen because PCI io usually starts
at 1000 but in general it might be above 1000 too. I think this was the reason
for this quirk. - The ACPI pnp might claim this region too and in fact ACPI
should do that. Even more specially this quirk is here mostly when ACPI fails to
do so and the IO is above 1000 ;)

You may ignore this as mostly harmless.  No really it is harmless for you.

Thanks,
