-U-BOOT Port for FSForth ModNET50 Board
---------------------------------------
-
-author: Thomas Elste <info@elste.org>
- IMMS gGmbH <www.imms.de>
-
-The port based upon an early (partial complete)
-armboot-port from Stephan Linz for the ModNET50 Board.
-
-
-Overview:
-
-- board with Netsilicon NET+50 ARM7TDMI CPU without MMU
-- 16 MB SDRAM
-- 2 MB Flash (MBL29LV160BE)
-- 10/100 Ethernet PHY (LXT971A)
-
-
-Current Configuration (include/configs/modnet50.h):
-
-Memory Map: 0x00000000 - 0x00FFFFFF 16M SDRAM
- 0x10000000 - 0x101FFFFF 2M Flash
-
-The Flash uses a BB-Architectur with 35 sectors
-(0:16K; 1,2:8K; 3:32K; 4-34:64K). U-Boot is located in
-the first 5 sectors.
-
-The environment is located at the end of the 4th Flash
-sector (0x1001C000-0x1001FFFF).
-
-Build:
-
-U-boot should be build by using the ELDK Toolchain (arm-linux-*).
-
- make modnet50_config
- make
-
-
-Status:
-
-Everything seems to work fine. Booting images was tested by
-booting uCLinux (with and without a separate ramdisk image) from
-flash.
-
