7The port based upon an early (partial complete)
8armboot-port from Stephan Linz for the ModNET50 Board.

11Overview:
12
13- board with Netsilicon NET+50 ARM7TDMI CPU without MMU
14- 16 MB SDRAM
15- 2 MB Flash (MBL29LV160BE)
16- 10/100 Ethernet PHY (LXT971A)

19Current Configuration (include/configs/modnet50.h):
20
21Memory Map: 0x00000000 - 0x00FFFFFF 16M SDRAM
wdenkcd0a9de2004-02-23 20:48:38 +000022 0x10000000 - 0x101FFFFF 2M Flash
wdenk2d1a5372004-02-23 19:30:57 +000023
24The Flash uses a BB-Architectur with 35 sectors
25(0:16K; 1,2:8K; 3:32K; 4-34:64K). U-Boot is located in
26the first 5 sectors.
27
28The environment is located at the end of the 4th Flash
29sector (0x1001C000-0x1001FFFF).

31Build:
32
33U-boot should be build by using the ELDK Toolchain (arm-linux-*).

35 make modnet50_config
36 make

39Status:
40
41Everything seems to work fine. Booting images was tested by
42booting uCLinux (with and without a separate ramdisk image) from
43flash.
