Dear Bin:

I have a suggetion that the acpi specification definition such as all acpi table structure definition  should be place in /include directory.
and write_acpi_tables function can be placed in platform directory.  Creating acpi table mothod  can be diffrent between x86 and arm.

Thank you
Steven Hao

It can not be used to arm plateform. If the acpi library need to surport for all platform,i think it should move to /include directory.

Yes, we all are aware that modifications are needed to the existing
x86 ACPI support to support ARM. We don't want to create 2 ACP
implementation in U-Boot.
