I think you could use one of the machines that has a cfi02 on board. For
example: Write some random data to a temporary file. Run qemu with:
QTestState *qts;
qts = qtest_initf(" qemu-system-arm -M musicpal,accel=qtest "
"-drive if=pflash,file=%s,format=raw", filename);
Then you should be able to access the device with the qtest_read/write
functions, e.g. use "qtest_memread(qts, 0x100000000ULL, ...)" to read
the contents of the device. I haven't tried that though, that's just my
quick assumption from looking at hw/arm/musicpal.c ...
