From 3a25075ecef85adca5ab5b4e2486955b9d7a23ce Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Fri, 6 Dec 2024 18:10:20 +0100 Subject: [PATCH] hw/nvram/fw_cfg: Remove fw_cfg_add_extra_pci_roots() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that all uses of fw_cfg_add_extra_pci_roots() have been converted to the newer pci_bus_add_fw_cfg_extra_pci_roots(), we can remove that bogus method. hw/nvram/fw_cfg must stay generic. Device specific entries have to be implemented using TYPE_FW_CFG_DATA_GENERATOR_INTERFACE. This mostly reverts commit 0abd38885ac0fcdb08653922f339849cad387961 ("fw_cfg: Refactor extra pci roots addition"). Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Daniel P.
