Add AML dump option without concatinating SSDT's memory image

[takawata]

Summary

In some machine, like my ThinkPad X16, concatenate byte code will cause error in AML dump with iasl due to symbol duplicate. It is resolved by invoking iasl separately for each DSDT and SSDT's.

This patch add -s option to dump AML byte code without concatinating DSDT and SSDT's. Instead, It will concatenate output of iasl for each DSDT and SSDT's.

Test Plan

compile and invoke with

acpidump -s under

appropriate permission.

I suspect that this 'separate' mode is how it is supposed to be evaluated and disassembled. Should we change to it, and flag to indicate to use concatenation?

etc please follow style

With this patch , the -s option will produce multiple DefinitionBlock() for each SSDT 's in addtion to for DSDT,
on the contrary the -d option will produce a single DefinitionBlock() for DSDT.

-s output may not use DSDT override base, but with -d option will produce following output in my machine.

% acpidump -dv
will generate

Ok. Please fix the style issues.

[takawata]

style nits.

Please fix these remaining style issues before committing.

The man page should describe the new option (can be a follow-up change).
