When only using CONFIG_POWERNV=y in the default-config and using
"configure --without-default-devices --target-list=ppc64-softmmu" I
still get a linking error:
LINK ppc64-softmmu/qemu-system-ppc64
hw/ppc/pnv.o: In function `pnv_init':
hw/ppc/pnv.c:846: undefined reference to `serial_hds_isa_init'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:206: qemu-system-ppc64] Error 1
Looks like there is still a "select SERIAL" or something similar missing
here?
