* DynamicTablesPkg: Rename SBSA generic watchdogChris Jones2021-10-051-30/+30
| | | | | | | | | | | | | Buzilla: 3565 (https://bugzilla.tianocore.org/show_bug.cgi?id=3565) As part of the updates to ACPI 6.4 the "SBSA Generic Watchdog" was renamed to the "Arm Generic Watchdog". This patch implements that change by updating the GTDT generator to use Acpi64.h and renames any occurence of "SBSA Generic Watchdog" to "Arm Generic Watchdog".

* DynamicTablesPkg: Fix GT Block length assignmentSami Mujawar2020-03-291-4/+21
| | | | | | | | | | | | | | | | | | The VS2017 compiler reports 'warning C4267: '=': conversion from 'size_t' to 'UINT16', possible loss of data'. The sizeof() operator is used to calculate the size of the GT Block structure. The length field in the GT Block structure is 16-bit wide. Since the return type of sizeof() operator is size_t the VS2017 compiler reports the above warning. To fix the warning, an explicit type cast is added. An additional check is also performed to ensure that the calculated GT Block length does not exceed MAX_UINT16.

* DynamicTablesPkg: Fix entry point param definitionSami Mujawar2020-03-291-4/+4
| | | | | | | | | | | | | | VS2017 reports 'warning C4028: formal parameter 2 different from declaration' for the library constructor and destructor interfaces for the Generator modules. VS2017 compiler also reports similar warnings for the DXE entry points. Remove the CONST qualifier for the SystemTable pointer (the second parameter to the constructor/destructor/DXE Entry point) to make it compatible with the formal declaration.

* DynamicTablesPkg: Arm ACPI GTDT GeneratorSami Mujawar2019-02-191-0/+700
The GTDT generator uses the configuration manager protocol to obtain information about the architectural and platform timers available on the platform and generates the ACPI GTDT table. This table data is then used by the Table Manager to install the GTDT table. The Table Manager then invokes the generator interface to free any resources allocated by the GTDT table generator.
