[v2] Implement a FdtHwInfoParserLib

[edk2-devel] [PATCH v2 15/15] DynamicTablesPkg: Handle 16550_WITH_GAS id
Posted by PierreGondois 4 years, 2 months ago
From: Pierre Gondois <Pierre.Gondois@arm.com>

Handle the EFI_ACPI_DBG2_PORT_SUBTYPE_SERIAL_16550_WITH_GAS
id when generating an AML description of a serial port. The same
_HID/_CID as the EFI_ACPI_DBG2_PORT_SUBTYPE_SERIAL_FULL_16550
are generated.
