Arcangel4 is a FPGA-based development board that is used for prototyping and
verificationof of both ARC hardware (CPUs) and software running upon CPU.

This board avaialble in 2 flavours:
 * Little-endian (arcangel4)
 * Big-endian (arcangel4-be)

Changes for v4:
 * Removed common CONFIG_SYS_BAUDRATE_TABLE
 * Removed MEMTEST-related definitions as suggested by Wolfgang

Note there's a prerequisite - http://patchwork.ozlabs.org/patch/300901/

+# This board is mostly used for debugging U-Boot in simulation (ISS).
+# The only peripheral which is used on this board is a serial port which

+# And now there's no specific initializations for this board.
+# So this Makefile is only required for satisfaction of U-Boot build system.
