Optimize use of system and secondary disks

Not all systems support eMMC, but where possible, use eMMC to optimize your boot time. In your buildfile, ensure that you include a script section to start the appropriate driver for your target hardware. For example:

...
[+script] .script = {
    display_msg Starting eMMC as system disk /dev/sysdisk0 ...
    # START eMMC
    devb-sdmmc-omap_generic sdio
    lk=192000000,addr=0x480B4000,irq=118,hc=omap,bs=emmc:bw=8
    blk cache=2M disk name=emmc
}
...
