[PATCH v2 08/12] aspeed: Create flash devices only when defaults are enabled

[Cédric Le Goater]

When the -nodefaults option is set, flash devices should be created
with :

    -blockdev node-name=fmc0,driver=file,filename=./flash.img \
    -device mx66u51235f,addr=0x0,bus=ssi.0,drive=fmc0 \

To be noted that in this case, the ROM will not be installed and the
initial boot sequence (U-Boot loading) will fetch instructions using
SPI transactions which is significantly slower. That's exactly how HW
operates though.
