[Qemu-ppc] [PATCH 0/2] ppc: Allow "-prom-env" parameter for the pseries machine, too

[Thomas Huth]

Here's a slightly updated version of the patch that enables the "-prom-env"
parameter for the pseries machine. The code is now only executed if
nb_prom_envs > 0. That means if the user did _not_ specify a "-prom-env"
parameter, there is no change in behavior (i.e. SLOF will initialize the
NVRAM instead). This fixes the problem with grub2 not working because it does
not find the "/options/real-mode?" property in the device tree.

If you currently want to use the "-prom-env" parameter and grub2 together,
you simply have to specify -prom-env "real-mode?=true" to get it working.
This will be fixed by a later update to SLOF, so that you then do not have to
specify this explicitely anymore.

The second patch adds a test case for the -prom-env parameter on the
pseries machine.

The patches have to be applied on top of David's ppc-for-2.8 branch since
they rely on the chrp_nvram rework patches that are queued there.

Thomas Huth (2):
  spapr_nvram: Pre-initialize the NVRAM to support the -prom-env
    parameter
  tests: Add pseries machine to the prom-env-test, too
