+A word on the U-Boot enviroment variable setting and usage :
+
+In the beginning, you could just need very simple defult environment variable setting,
+like[include/configs/RPXlite.h] :
+
+#define CONFIG_BOOTCOMMAND                                                      \

+This is enough for kernel NFS test. But as debug process goes on, you would expect

+So the default environment variable setting would become more complicated. Just like

+'100000' and then use them correctly. Yeah, you can create your own command to do this
+job. :-) The example u-boot image updating process could be :

+
+
+CONFIGURING
+-----------
+
+1. Modify include/configs/cobra5272.h acc. to your prefs
+
+2. If necessary, modify board/cobra5272/config.mk (see below)
+
+3.
+
+> make cobra5272_config
+
+> make
+
+
+Please refer to u-boot README (general info, u-boot-x-x-x/README),
+to u-boot-x-x-x/doc/README.COBRA5272 and
+to the comments in u-boot-x-x-x/include/configs/cobra5272.h
+
+Configuring u-boot is done by commenting/uncommenting preprocessor defines.
+
+Default configuration is
+
+	FLASH version (for further info see subsection below)
+	link address 0xffe00000
+
+	16 MB RAM
+
+	network enabled
+	no default IP address for target, host set, no MACaddress set
+
+	bootdelay for autoboot 5 sec.
+	autoboot disabled
+
+
+#-----------------------------------
+# u-boot FLASH version & RAM version
+#-----------------------------------
+
+The u-boot bootloader for Coldfire processors can be configured
+
+	1. as a standalone bootloader residing in flash & relocating itself to RAM on
+	startup automatically => "FLASH version"
+
+	2. as a RAM version which will not load from flash automatically as it needs a
+	prestage bootloader ("chainloading") & is running only from the RAM address it
+	is linked to => "RAM version"
+
+	This version may be very helpful when installing u-boot for the first time
+	since it can be used to make available s. th. like a "bootstrap
+	mechanism".
+
+
+How to build the different images:
+
+------------------------------
+Flash version
+------------------------------
+
+Compile u-boot
+
+in dir ./u-boot-x-x-x/
+
+please first check:
+
+	in ./include/configs/cobra5272.h
+
+		CONFIG_MONITOR_IS_IN_RAM has to be undefined, e. g. as follows:
+
+		#if 0
+			#define CONFIG_MONITOR_IS_IN_RAM
+			/* define if monitor is started from a pre-loader */
+		#endif
+
+	=> u-boot as single bootloader starting from flash
+
+
+	in board/cobra5272/config.mk TEXT_BASE should be
+
+		TEXT_BASE = 0xffe00000
+
+	=> linking address for u-boot as single bootloader stored in flash
+
+then:
+
+	host> make cobra5272_config
+		rm -f include/config.h include/config.mk
+		Configuring for cobra5272 board...
+	host> make
+		[...]
+
+	host> cp u-boot.bin /tftpboot/u-boot_flash.bin
+
+
+------------------------------
+RAM version
+------------------------------
+
+in dir ./u-boot-x-x-x/
+
+	host> make distclean
+
+please modify the settings:
+
+	in ./include/configs/cobra5272.h
+
+		CONFIG_MONITOR_IS_IN_RAM now has to be defined, e. g. as follows:
+
+		#if 1
+			#define CONFIG_MONITOR_IS_IN_RAM
+			/*define if monitor is started from a pre-loader */
+		#endif
+
+	=> u-boot as RAM version, chainloaded by another bootloader or using bdm cable
+
+
+	in board/cobra5272/config.mk TEXT_BASE should be
+
+		TEXT_BASE = 0x00020000
+
+	=> target linking address for RAM
+
+
+then:
+
+	host> make cobra5272_config
+		rm -f include/config.h include/config.mk
+		Configuring for cobra5272 board...
+	host> make
+		[...]
+
+	host> cp u-boot.bin /tftpboot/u-boot_ram.bin
+
+
+----
+HINT
+----
+
+If the m68k-elf-toolchain & the m68k-bdm-gdb is installed you can run the RAM
+version by typing (in dir ./u-boot-x-x-x/)
+"board/cobra5272/bdm/load-cobra_uboot" ,
+in ./u-boot-x-x-x/ the RAM version u-boot (elf format) has to be available.

+This driver supports NE2000 compatible cards (those based on DP8390,
+DP83902 and similar). It can be used with PCMCIA/CF cards provided
+that the CCR is correctly initialized.
+
+The code is based on sources from the Linux kernel (pcnet_cs.c,
+8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2
+wonderful world are GPL, so this is, of course, GPL.
+
+I developed and tested this driver on a custom PXA255 based system and
+with a billionton CF network card connected to the PCMCIA interface of
+the micro (have a look at README.PXA_CF for the support of this port).
+
+The options you have to specify in the config file are (with the
+value for my board as an example):
+
+#define CONFIG_DRIVER_NE2000
+
+- Enables the driver
+
+#define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300)
+
+- Address where the board is mapped
+
+#define CONFIG_DRIVER_NE2000_CCR (0x28000000+0x3f8)
+
+- Address of the CCR (card configuration register). It could be found
+by enabling DEBUG in cmd_pcmcia.c. If this is not defined nothing is
+done as far as PCMCIA support is concerned.
+
+#define CONFIG_DRIVER_NE2000_VAL (0x20)
+
+- The value to be written in the CCR. It selects among different I/O
+spaces that could be used by the card.
+
+
+Enjoy!
