+______________________________________________________________________
+
+
+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.
