Build
=====
First, load socrates config for buildroot
make socrates_cyclone5_defconfig
Build everything
make
Following files will be generated in output/images

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.
