Patches by Stephan Linz, 30 Jan 2004:

1: - board/altera/common/flash.c:flash_erase():
     o allow interrupts befor get_timer() call
     o check-up each erased sector and avoid unexpected timeouts
   - board/altera/dk1c20/dk1s10.c:board_early_init_f():
     o enclose sevenseg_set() in cpp condition
   - remove the ASMI configuration for DK1S10_standard_32 (never present)
   - fix some typed in mistakes in the NIOS documentation
2: - split DK1C20 configuration into several header files:
     o two new files for each NIOS CPU description
     o U-Boot related part is remaining in DK1C20.h
3: - split DK1S10 configuration into several header files:
     o two new files for each NIOS CPU description
     o U-Boot related part is remaining in DK1S10.h
4: - Add support for the Microtronix Linux Development Kit
     NIOS CPU configuration at the Altera Nios Development Kit,
     Stratix Edition (DK-1S10)
5: - Add documentation for the Altera Nios Development Kit,
     Stratix Edition (DK-1S10)
6: - Add support for the Nios Serial Peripharel Interface (SPI)
     (master only)
7: - Add support for the common U-Boot SPI framework at
     RTC driver DS1306
