Patches by Stephan Linz, 11 Dec 2003:
- more documentation for NIOS port - new struct nios_pio_t, struct nios_spi_t - Reconfiguration for NIOS Development Kit DK1C20: o move board related code from board/dk1c20 to board/altera/dk1c20 o create a new common source path board/altera/common and move generic flash access stuff into it o change/expand configuration file DK1C20.h - Add support for NIOS Development Kit DK1S10 - Add status LED support for NIOS systems - Add dual 7-segment LED support for Altera NIOS DevKits
