[Qemu-devel] [PATCH 1/5] boot: extend get_boot_devices_list() to ignore suffixes |
Date: |
Mon, 25 Nov 2013 18:27:36 +1100 |
As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.
