+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.
