Since v1:
- Do not introduce pflash_cfi_create(), directly
open-code pflash_cfi_register() before removing it (Peter)
- Added R-b tags
Paving the road toward heterogeneous QEMU, the limitations of
having a single machine sysbus become more apparent.
The sysbus_mmio_map() API forces the caller to map a sysbus
device to an address on the system bus (system bus here is
the root MemoryRegion returned by get_system_memory() ).
This is not practical when each core has its own address
space and group of cores have access to a part of the
peripherals.
Experimenting with the PFLASH devices. Here the fix is
quite easy: open-code the pflash_cfi_register() functions.
Since we were touching the PFLASH API, we restricted the
PFlashCFI0X structures to their models. The API now deals
with a generic qdev pointer (DeviceState*).
Please review,
Phil.
