0002 =====
0003
0004  Goal is to have BSPs build almost completely automatically from a template
0005  and information that comes from SOPC Builder as a .PTF file. Most of the
0006  code will go to a shared/ BSP directory.
0007
0008  Ideally, updates to the PTF shouldn't cause any pain for the maintainer
0009  of a specific BSP (possibly with enhancements not covered by the
0010  automatic BSP creation).
0011
0012  Some first steps toward utilizing SOPC Builder PTF output can be found
0013  in top level /tools/cpu/nios2. Also see the README there.
0014
0015   Implemented (in shared/ subdirectory)
0016     Clock driver
0017     Timer driver
0018     Console via JTAG UART
0019
0020   Todo;
0021     Support more peripherals. My priorities:
0022       - (improve) Altera Avalon JTAG UART
0023       - Altera Avalon UART
0024       - OpenCores.org I2C Master
0025       - Altera SPI Core / EPCS Configuration Device
0026       - OpenCores.org 10/100 Ethernet MAC (use existing driver)
0027       - (more) Altera Avalon Timer
0028
0029     Put all drivers aside in a shared/ subdirectory.
0030     Update the "times" file for NIOS2 with and without icache.
0031
0032   Missing (although it looks like it's there)
0033     Data cache handling (for now, don't use the "fast" NIOS2)
0034     SHM support (just taken over the code from no_cpu/no_bsp)
