# File:    Makefile
# Author:  David Burnette
# Date:    April 7, 2008
#
# Description:
#  This makefile generates a VHDL file from assembler source.
#  A translate rule in mktargets.mk handles compiling the .asm
#  into a S19 record file (.S19) and then running s19tovhd to
#  generate a VHDL file with SPARTAN3 block rams with INIT generics
#  containing the binary data.
#
#  This particular makefile handles generating FLEX9 code.
#
# Usage:
#  This make file is called recursively by the board-specific
#  makefiles in the 'rtl' directory. The targets generated by
#  this makefile are:
#
#    make                     - makes all variants
#    make all                 - makes all variants
#    make flex9ide.vhd        - for IDE disk (Xess board)
#    make flex9cf8.vhd        - for CompactFlash (Burched boards)
#    make flex9ram.vhd        - for RAM disk (Spartan3 starter)
#    make flex9ads.vhd        -
#
# Target Descriptions:
#  The first file listed is the source file passed to assembler.
#  Remaining files are the dependencies. The option variables
#  ADDRS, ENTITY and TOP_RAM are used by the s19tovhd utility
#  to generate the VHDL file.
#
# Dependencies:
#  This makefile depends on def_rules.mk and the top-level
#  ram model file flex_ram_vhd.
