ACPICA version 20090123 released

[Moore, Robert]

23 January 2009. Summary of changes for version 20090123:

This release is available at www.acpica.org/downloads.

1) ACPI CA Core Subsystem:

Added the 2009 copyright to all module headers and signons. This affects 
virtually every file in the ACPICA core subsystem, the iASL compiler, and 
the tools/utilities.

Implemented a change to allow the host to override any ACPI table, including dynamically loaded tables. Previously, only the DSDT could be replaced by the host. With this change, the AcpiOsTableOverride interface is called for each table found in the RSDT/XSDT during ACPICA initialization, and also whenever a table is dynamically loaded via the AML Load operator.

Updated FADT flag definitions, especially the Boot Architecture flags.

Debugger: For the Find command, automatically pad the input ACPI name with underscores if the name is shorter than 4 characters. This enables a match with the actual namespace entry which is itself padded with underscores.

Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

Fix build error under Bison-2.4.

Dissasembler: Enhanced FADT support. Added decoding of the Boot Architecture flags. Now decode all flags, regardless of the FADT version. Flag output includes the FADT version which first defined each flag.

The iASL -g option now dumps the RSDT to a file (in addition to the FADT and DSDT). Windows only.
