From ec0503b4f0a37b55fedc164185369bf5f0030f7b Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 30 May 2013 12:13:06 +0300 Subject: firmware_abi: move to include/hw/nvram/ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit firmware_abi.h with structs for OpenBIOS landed in hw/sparc/ by mistake - move it to hw/nvram/ alongside fw_cfg.h. In addition to sparc it's included from ppc mac_nvram.c and will need to include it from prep.c in the future. Acked-by: Andreas Färber Signed-off-by: Michael S.
