Subject: [PATCH 37/78] hw/loongarch: Add acpi SPCR table support
|
|
|
|
Serial port console redirection table can be used for default serial
|
|
port selection, like chosen stdout-path selection with FDT method.
|
|
|
|
With acpi SPCR table added, early debug console can be parsed from
|
|
SPCR table with simple kernel parameter earlycon rather than
|
|
earlycon=uart,mmio,0x1fe001e0
