Creating bootable SD card
=========================

Simply invoke

dd if=output/images/sdcard.img of=/dev/sdX

Where X is your SD card device (not partition)

Booting
=======

Pins 6:8 on P18 selector is used to determine boot device. To boot socrates from
sdcard set these pins to value 0x5 (101b). Remaining pins are used to determine
how to configure FPGA and are not associated with booting into Linux kernel.
