4#  Goal is to have BSPs build almost completely automatically from a template
5#  and information that comes from SOPC Builder as a .PTF file. Most of the
6#  code will go to a shared/ BSP directory.
7#
8#  Ideally, updates to the PTF shouldn't cause any pain for the maintainer
9#  of a specific BSP (possibly with enhancements not covered by the
10#  automatic BSP creation).
11#
12#  Some first steps toward utilizing SOPC Builder PTF output can be found
13#  in top level /tools/cpu/nios2. Also see the README there.
14#
15#   Implemented (in shared/ subdirectory)
16#     Clock driver
17#     Timer driver
18#     Console via JTAG UART
19#
20#   Todo;
21#     Support more peripherals. My priorities:
22#       - (improve) Altera Avalon JTAG UART
23#       - Altera Avalon UART
24#       - OpenCores.org I2C Master
25#       - Altera SPI Core / EPCS Configuration Device
26#       - OpenCores.org 10/100 Ethernet MAC (use existing driver)
27#       - (more) Altera Avalon Timer
28#
29#     Put all drivers aside in a shared/ subdirectory.
30#     Update the "times" file for NIOS2 with and without icache.
31#
32#   Missing (although it looks like it's there)
33#     Data cache handling (for now, don't use the "fast" NIOS2)
34#     SHM support (just taken over the code from no_cpu/no_bsp)
