configs/socrates_cyclone5: new defconfig

Configuration contains:
  - building uboot (and spl) from altera's github
  - booting from SD card
  - working ethernet, serial, i2c, fpga_manager
  - minimal rootfs with busybox
  - ready to flash SD card image

+EBV SoCrates Evaluation Board
+
+Intro
+=====
+
+More information about this board can be found here:
+https://rocketboards.org/foswiki/Documentation/EBVSoCratesEvaluationBoard
+
+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.
