This is what's in qemu/include/hw/ppc/ppc.h:

#define FW_CFG_PPC_WIDTH        (FW_CFG_ARCH_LOCAL + 0x00)
#define FW_CFG_PPC_HEIGHT       (FW_CFG_ARCH_LOCAL + 0x01)
#define FW_CFG_PPC_DEPTH        (FW_CFG_ARCH_LOCAL + 0x02)
#define FW_CFG_PPC_TBFREQ       (FW_CFG_ARCH_LOCAL + 0x03)
#define FW_CFG_PPC_CLOCKFREQ    (FW_CFG_ARCH_LOCAL + 0x04)
#define FW_CFG_PPC_IS_KVM       (FW_CFG_ARCH_LOCAL + 0x05)
#define FW_CFG_PPC_KVM_HC       (FW_CFG_ARCH_LOCAL + 0x06)
#define FW_CFG_PPC_KVM_PID      (FW_CFG_ARCH_LOCAL + 0x07)

And this is what's in openbios-devel/include/arch/common/fw_cfg.h:

#define FW_CFG_PPC_WIDTH        (FW_CFG_ARCH_LOCAL + 0x00)
#define FW_CFG_PPC_HEIGHT       (FW_CFG_ARCH_LOCAL + 0x01)
#define FW_CFG_PPC_DEPTH        (FW_CFG_ARCH_LOCAL + 0x02)
#define FW_CFG_PPC_TBFREQ       (FW_CFG_ARCH_LOCAL + 0x03)
#define FW_CFG_PPC_CLOCKFREQ    (FW_CFG_ARCH_LOCAL + 0x04)
#define FW_CFG_PPC_IS_KVM       (FW_CFG_ARCH_LOCAL + 0x05)
#define FW_CFG_PPC_KVM_HC       (FW_CFG_ARCH_LOCAL + 0x06)
#define FW_CFG_PPC_KVM_PID      (FW_CFG_ARCH_LOCAL + 0x07)
#define FW_CFG_PPC_NVRAM_ADDR   (FW_CFG_ARCH_LOCAL + 0x08)

Should I add new FW_CFG values with a gap (or adding an unused 
FW_CFG_PPC_NVRAM_ADDR to qemu) or should I renumber these ti add 
FW_CFG_PPC_BUSFREQ grouped with the other FREQ values?

Regards,
