[Qemu-devel] [RFC PATCH 09/11] hw/acpi/acpi-build-utils: Add acpi_fixed_memory32() and acpi_extended_irq() |
Date: |
Sat, 24 Jan 2015 17:21:18 +0800 |
Add acpi_fixed_memory32() for describing device mmio region in resource
template.
Add acpi_extended_irq() for describing device interrupt in resource template.
These can be used to generating DSDT table for ACPI on ARM.
