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

+# 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
+# requires no initialization except those in "include/configs/arcangel4.h".
+# And now there's no specific initializations for this board.
+# So this Makefile is only required for satisfaction of U-Boot build system.
