The Platform Communications Channel Table (Pcct) allows to communicate
by describing mailboxes. Make use of the DynamicTablesPkg to generate
this table.
This patch-set also contains:
- Fixes for the CmObjParser,
- Removal of deprecated APIs
- Renaming for some of the PCCT fields
Pierre Gondois (14):
DynamicTablesPkg: Use correct print formatter
DynamicTablesPkg: Add PrintString to CmObjParser
DynamicTablesPkg: Update CmObjParser for IORT Rev E.d
DynamicTablesPkg: Update CmObjParser for MinorRevision
DynamicTablesPkg: Fix GTBlock and GTBlockTimerFrame CmObjParsers
DynamicTablesPkg: Fix wrong/missing fields in CmObjParser
DynamicTablesPkg: Remove deprecated APIs
DynamicTablesPkg: FdtHwInfoParserLib: Remove wrong comment
DynamicTablesPkg: Fix Ssdt PCI generation comments
DynamicTablesPkg: Add PCCT related objects
DynamicTablesPkg: Add PCCT Generator

In C, the 'long long' types are 64-bits. The 'll' printf length
specifier should be used to pring these values. Just '%x' allows to
print values that are on 16-bits or more. Use that instead.

Add a PrintString to print strings in the CmObjParser.
String must be NULL terminated and no buffer overrun check
is done by this function.

The CmObjParsers of the following objects was inverted, probably
due to a wrong ordering placement in the file defining the structures:
-EArmObjGTBlockTimerFrameInfo
-EArmObjPlatformGTBlockInfo
Assign the correct parser for each object, and re-order the
structures in the file defining them.

The second model of the _PRT object is used. Indeed:
- the interrupts described are not re-configurable
- OSes are aware of the polarity of PCI legacy interrupts,
so there is no need to accurately describe the polarity.
Also, fix a comment for the CM_ARM_PCI_INTERRUPT_MAP_INFO obj.

- CM_ARM_MAILBOX_REGISTER_INFO
- CM_ARM_PCC_SUBSPACE_CHANNEL_TIMING_INFO
- CM_ARM_PCC_SUBSPACE_GENERIC_INFO
- CM_ARM_PCC_SUBPSACE_TYPE0_INFO

- CM_ARM_PCC_SUBPSACE_TYPE3_INFO
- CM_ARM_PCC_SUBPSACE_TYPE4_INFO
- CM_ARM_PCC_SUBPSACE_TYPE5_INFO
These objects allow to describe mailbox registers, pcc timings
and PCCT subspaces. They prepare the enablement of a PCCT generator.
Also add the CmObjParsers associated to each object.

From: PierreGondois @ 2022-10-10 9:20 UTC (permalink / raw)
To: devel; +Cc: Sami Mujawar, Alexei Fedorov
From: Pierre Gondois <pierre.gondois@arm.com>
The Platform Communication Channel Table (PCCT) generator collates
the relevant information required for generating a PCCT table from
configuration manager using the configuration manager protocol.
The DynamicTablesManager then install the PCCT table.
>From ACPI 6.4, s14 PLATFORM COMMUNICATIONS CHANNEL (PCC):
The platform communication channel (PCC) is a generic mechanism
for OSPM to communicate with an entity in the platform.

I have one comment marked inline as [SAMI].
I believe other than that change this patch should be good.

[SAMI] The changes in ConfigurationManagerObjectParser.c should be in
the previous patch 10/14. Otherise it would break git bisect.
If you agree, I will move the changes in
ConfigurationManagerObjectParser.c in patch 10/14 before merging.
