  To: buildroot

From: Micha? ?yszczek <michal.lyszczek@bofc.pl>

Configuration contains:
  - binary uboot SPL
  - building uboot from altera's github
  - booting from SD card
  - working ethernet, serial, spi, i2c, fpga_manager, gpio
  - minimal rootfs with busybox (~3.5Mb)
  - ready to flash SD card image

Signed-off-by: Micha? ?yszczek <michal.lyszczek@bofc.pl>

---
Changes v1 -> v2:
  - removed binary SPL (all compiled from source now)

+EBV SoCrates Evaluation Board
+
+Intro
+=====
+
+More information about 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
+
+.
+??? boot.scr
+??? boot.vfat
+??? boot_partition.img
+??? linux.dtb
+??? preloader.bin
+??? rootfs.ext2
+??? rootfs.ext4 -> rootfs.ext2
+??? rootfs.tar
+??? sdcard.img
+??? u-boot.bin
+??? u-boot.img
+??? uboot-env.bin
+??? zImage
+
+
+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). Rest pins are used to determine how
+to configure FPGA and are not associate with booting into Linux kernel.
