This is the same layout that is also used by the PAPR specification and thus by the SLOF firmware of the pseries machine. By refactoring the NVRAM code from mac_nvram.c, we can use the same functions for setting up the NVRAM for both, OpenBIOS and SLOF. This way we can support the "-prom-env" parameter of QEMU for SLOF, too, which is very useful to influence the firmware boot process. Thomas Huth (5): nvram: Introduce helper functions for CHRP "system" and "free space" partitions sparc: Use the new common NVRAM functions for system and free space partition spapr_nvram: Pre-initialize the NVRAM to support the -prom-env parameter nvram: Move the remaining CHRP NVRAM related code to chrp_nvram.[ch] nvram: Rename openbios_firmware_abi.h into sun_nvram.h hw/nvram/Makefile.objs | 1 + hw/nvram/chrp_nvram.c | 85 ++++++++++++++++++++++ hw/nvram/mac_nvram.c | 49 +++---------- hw/nvram/spapr_nvram.c | 6 ++ hw/sparc/sun4m.c | 35 ++------- hw/sparc64/sun4u.c | 35 ++------- include/hw/nvram/chrp_nvram.h | 54 ++++++++++++++ .../nvram/{openbios_firmware_abi.h => sun_nvram.h} | 47 +----------- tests/postcopy-test.c | 8 +- 9 files changed, 179 insertions(+), 141 deletions(-) create mode 100644 hw/nvram/chrp_nvram.c create mode 100644 include/hw/nvram/chrp_nvram.h rename include/hw/nvram/{openbios_firmware_abi.h => sun_nvram.h} (50%) -- 1.8.3.1
