I am missing something ? I rebuilt all available targets before
commiting... but I now see sparc64-softmmu seems not to be in the
available targets, which could explain I cannot check if it compiles or
not...  As it been removed by mistake ?

You mean the NVRAM_set / get_xxx ? I was to remove the definitions from
vl.h, I have to say, because those are supposed to be PowerPC (in fact
OpenHack'Ware) related hacks.
Those functions will never go in m48t59.h as they are not related with
m48t59. Apple machine don't have such a device (even if Qemu pretend it
has, this is to be removed in the days to come) but need those functions
to pass arguments to the firmware. What I needed to do (and that what I
did commit) is make those routines independant from m48t59 so I can
remove this device from ppc_chrp.c and ppc_oldworld.c and use the real
Mac nvram instead (but ppc_prep.c still uses m48t59...).

Whatever, I'll try to fix the sparc64 case as I broke it (if I found the
code ;-) ).
