#
# $Id$
#
# Goal is to have BSPs build almost completely automatically from a template
# and information that comes from SOPC Builder as a .PTF file. Most of the
# code will go to a shared/ BSP directory.
#
# Ideally, updates to the PTF shouldn't cause any pain for the maintainer
# of a specific BSP (possibly with enhancements not covered by the
# automatic BSP creation).
#
# Some first steps toward utilizing SOPC Builder PTF output can be found
# in top level /tools/cpu/nios2. Also see the README there.
#
# Implemented (in shared/ subdirectory)
# Clock driver
# Timer driver
# Console via JTAG UART
#
# Todo;
# Support more peripherals. My priorities:
# - (improve) Altera Avalon JTAG UART
# - Altera Avalon UART
# - OpenCores.org I2C Master
# - Altera SPI Core / EPCS Configuration Device
# - OpenCores.org 10/100 Ethernet MAC (use existing driver)
# - (more) Altera Avalon Timer
#
# Put all drivers aside in a shared/ subdirectory.
# Update the "times" file for NIOS2 with and without icache.
#
# Missing (although it looks like it's there)
# Data cache handling (for now, don't use the "fast" NIOS2)
# SHM support (just taken over the code from no_cpu/no_bsp)
