[edk2-devel] [PATCH v3 5/6] [edk2-platforms] Silicon/SynQuacer: add DBG2 ACPI table
Posted by Masami Hiramatsu 4 years ago 
Add DBG2 table to ACPI tables. The COM1 uart port will be used
for OS debug, and it is 16550 compatible.

Signed-off-by: Masami Hiramatsu <masami.hiramatsu@linaro.org>

  Changes in v2:
   - Move Dbg2.aslc before Dsdt.asl to keep the list alphabetically sorted.
   - Use EFI_ACPI_6_3_SYSTEM_MEMORY and EFI_ACPI_6_3_BYTE for initialization.

Hi Leif, Ard,

A gentle ping on this on behalf of Masami, since he left Linaro.

Thanks,
