[PATCH] ramdisk: Allow ramdisk support (CONFIG_FLASH_FLOPPY) under QEMU
Don't require coreboot to use CONFIG_FLASH_FLOPPY - with the latest QEMU, it's possible to place a floppy image into fw_cfg using the qemu command line (eg, "-fw_cfg name=floppyimg/MyFloppy,file=file.img").

FYI, I committed this patch (along with the timer and ps2 changes). -Kevin
