-#
-# cores: A list of cores to build. Use with the --section option.
-#
-# vfiles: A list of Verilog files to include in the vfiles list when
-# including a particular core. All (optional) cores must have a
-# vfiles option, so that the configuration program knows what to put
-# into core_vfiles.mk.
-#
-# requires: A list of other cores whose vfiles must be loaded to build
-# this core. This has no effect on the generated core_selector.v
-# file, and has no effect at all if an instance of a core named here
-# is already included in the build.
-#
-# error_wire: boolean indicating whether the core wants a error wire.
-#
-# block_memory: boolean indicating whether the core uses block memory.
-# Effect of this is a bit strange: setting it triggers generation of
-# a one-cycle timing delay for every core in this build that does
-# *not* use block memory. When no cores in the build use block
-# memory, the delay isn't necessary and is therefore omitted.

-# History of Cryptech bus addressing scheme, as best I understand it.
-#
-# The old old addressing scheme that Joachim and Paul came up with
-# was:
-#
-# 3 bits of segment selector [16:14]
-# 6 bits of core selector [13:8]
-# 8 bits of register selector [7:0]
-#
-# modexp6s needed more register bits than that, so Pavel changed
-# addressing within the math segment to:
-#
-# 3 bits of segment selector [16:14]
-# 4 bits of core selector [13:10]
-# 10 bits of register selector [9:0]
-#
-# Meanwhile, Paul eliminated segments entirely when writing the
-# ancestor of this script, resulting in:
-#
-# 9 bits of core selector [16:8]
-# 8 bits of register selector [7:0]
-#
-# Taking Pavel's and Paul's changes together, we'd get:
-#
-# 7 bits of core selector [16:10]
-# 10 bits of register selector [9:0]
-#
-# Except that this would waste space for most cores, and make things
-# very confusing for the TRNG cores. So, instead, we keep Paul's
-# two-level (no segment) scheme and handle modexps6 as a set of four
-# contiguous "cores" with a 10-bit composite register selector.
-
-# The modexps6 core drags in a one clock cycle delay to other cores,
-# to compensate for the extra clock cycle consumed by the block
-# memories used in the modexps6 core. We probably want a general
-# solution for this, because we're going to run into this problem for
-# any core that handles arguments big enough to require block memory.
-
-# To Do:
-#
-# - Consider automating the one-clock-cycle delay stuff by adding
-# another boolean flag to the config file. Default would be no
-# delay, if any included core sets the "I use block memories" flag,
-# all other cores would get the delay. Slightly tedious but
-# something we can calculate easily enough, and probably an
-# improvement over wiring in the delay when nothing needs it.
-#
-# - Rename script and its config file to something more meaningful.
-#
-# - Figure out whether this really belongs in the novena repository at
-# all, seems more generic than that.
