Subject: [PATCH 39/78] hw/loongarch/virt: Add FDT table support with acpi ged
|
|
pm register
|
|
|
|
ACPI ged is used for power management on LoongArch virt platform, in
|
|
general it is parsed from acpi table. However if system boot directly from
|
|
elf kernel, no UEFI bios is provided and acpi table cannot be used also.
|
|
|
|
Here acpi ged pm register is exposed with FDT table, it is compatbile
|
|
with syscon method in FDT table, only that acpi ged pm register is accessed
|
|
with 8-bit mode, rather with 32-bit mode.
