That should work.
It's already there (macio.c):
if (macio_state->escc_mem) {
memory_region_add_subregion(bar, 0x13000, macio_state->escc_mem);
}
I'll drop the extra mapping.
Well, it's not that easy. As the other mapping is part of an ordinary
BAR, you need to setup the device (at least PCI_COMMAND and
PCI_BASE_ADDRESS_0) so it responds to memory requests, and also enable
the bridge.
We could hack it by having a low-priority mapping at 0x80013000, but it
seems wrong. Maybe the firmware should configure that BAR first? What
happens on real hardware?
