A slow day today so here is a revised itest command with provisional
support for comparing strings as well :-))
Now table driven to allow the operators
-eq, -ne, -lt, -gt, -le, -ge, ==, !=, <>, <, >, <=, >=
Uses the expected command modifier for integer compares of width 1, 2 or
4 bytes of .b, .w, .l and the new modifer of .s for a string compare.
String comparison is over the length of the shorter, this hopefully
avoids missing terminators when using an indirect pointer.
eg.
if itest.l *40000 == 12345678 then; ....
if itest.w *40000 != 1234 then; ....
if itest.b *40000 >= 12 then; ....
if itest.s *40000 -eq hello then; ....

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.
