 Changes since U-Boot 1.0.1:
 ======================================================================
 
+* 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)

+====================================================================
+
+This file contains information regarding U-Boot and the Altera
+Nios Development Kit, Startix Edition (DK-1S10). For general Nios
+information see doc/README.nios.
+
+Most stuff of this file was borrowed and based on README.dk1c20,
+the DK-1C20 related information file.
+
+For those interested in contributing ... see HELP WANTED section
+in doc/README.nios.

+	include/configs/DK1S10.h
+
+2. Memory Organization
+=======================
+
+	-The heap is placed below the monitor (U-Boot code).
+	-Global data is placed below the heap.
+	-The stack is placed below global data (&grows down).
+
+3. CPU Variations
+=================
+
+There are more than one NIOS CPU variation for the DK-1S10. U-Boot
+supports the following CPU configurations:
+
+	- Altera Standard 32 (make DK1S10_standard_32_config)
+	- Microtronix LDK 2.0 (make DK1S10_mtx_ldk_20_config)
+
+4. Examples
+============
+
+The hello_world example was never tested on DK-1S10. Neverthelse
+it should work as far as possible, because the DK-1S10 port is
+more than ninetieth percents equal to the DK-1C20 port and at
+this platform the hello_world example was already tested
+successfully (see README.dk1c20).
+
+
+5. Programming U-Boot into FLASH with GERMS
+============================================
+The current version of the DK-1S10 port with the default
+configuration settings occupies about 78 KBytes of flash.
+A minimal configuration occupies less than 60 KByte
+(network support disabled).
+
+To program U-Boot into the DK-1S10 flash using GERMS do the
+following:
+
+1. From the command line, download U-Boot using the nios-run:
+
+	$ nios-run -r u-boot.srec
+
+This takes about 45 seconds (GERMS is not very speedy here).
+After u-boot is downloaded it will be executed. You should
+see the following:
+
+    U-Boot 1.0.2 (Jan 28 2004 - 19:02:30)
+
+    CPU: Nios-32 Rev. 3.3 (0x3038)
+    Reg file size: 256 LO_LIMIT/HI_LIMIT: 2/14
+    Board: Altera Nios 1S10 Development Kit
+    In:    serial
+    Out:   serial
+    Err:   serial
+    DK1S10 >
+
+
+2. Quit nios-run and start your terminal application (e.g. start
+   Hyperterminal or minicom).
+
+3. Download the u-boot code to RAM. When using Hyperterminal, do the
+   following:
+
+   a. From the u-boot command prompt start a binary download to
+      SRAM / SDRAM:
+
+      at the Altera Standard 32 to SRAM:
+
+	==> loadb 800000
+
+      at the Microtronix LDK 2.0 to SDRAM:
+
+	==> loadb 1010000
+
+   b. Download u-boot.bin using kermit.
+
+4. From the U-Boot command prompt, erase flash:
+
+   at the Altera Standard 32 from 0x40000 to 0x5ffff:
+
+	==> erase 1:4-5
+
+   at the Microtronix LDK 2.0 from 0x8000000 to 0x81ffff:
+
+	==> erase 1:0-1
+
+5. Copy the binary image from SRAM / SDRAM to flash:
+
+   at the Altera Standard 32 to SRAM:
+
+	==> cp.b 800000 40000 $(filesize)
+
+   at the Microtronix LDK 2.0 to SDRAM:
+
+	==> cp.b 1010000 8000000 $(filesize)
+
+U-Boot will now automatically start when the board is powered on or
+reset using the Standard-32 configuration. To start U-Boot with the
+Safe-32 configuration, enter the following GERMS command:
+
+    + g 40000
