+
+After following the step of Yoo. Jonghoon and Wolfgang Denk,
+I ported u-boot on RPXlite DW version board: RPXlite_DW or LITE_DW.
+
+There are three differences between the Yoo-ported RPXlite and the RPXlite_DW.
+
+Board(in U-BOOT)	version(in EmbeddedPlanet)	CPU	SDRAM	FLASH
+RPXlite				RPXlite CW		850	16MB	4MB
+RPXlite_DW			RPXlite DW		823e	64MB	16MB
+
+This fireware is specially coded for EmbeddedPlanet Co. Software Development
+Platform(RPXlite DW),which has a NEC NL6448BC20-08 LCD panel.
+
+It has the following three features:
+
+1. 64MHz/48MHz system frequence setting options.
+The default setting is 48MHz.To get a 64MHz u-boot,just add
+'64' in make command,like
+
+make RPXlite_DW_64_config
+make all
+
+2. CFG_ENV_IS_IN_FLASH/CFG_ENV_IS_IN_NVRAM
+
+The default environment parameter is stored in FLASH because it is a common choice for
+environment parameter.So I make NVRAM as backup parameter storeage.The reason why I
+didn't use EEPROM for ENV is that PlanetCore V2.0 use EEPROM as environment parameter
+home.Because of the possibility of using two firewares on this board,I didn't
+'disturb' EEPROM.To get NVRAM support,you may use the following build command:
+
+make RPXlite_DW_NVRAM_config
+make all
+
+3. LCD panel support
+
+To support the Platform better,I added LCD panel(NL6448BC20-08) function.But bewear of
+the fact that once you build this support and program it to FLASH,you should make sure
+you put workable kernel and ramdisk at the right place in FLASH or through NFS.
+Otherwise, you must erase this fireware manually via BDI2000 or ICE tools.So this
+function is used for deployment and demo only.Pls look before you leap.
+
+To get a LCD support u-boot,you can do the following:
+
+make RPXlite_DW_LCD_config
+make all
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The basic make commands could be:
+
+make RPXlite_DW_config
+make RPXlite_DW_64_config
+make RPXlite_DW_LCD_config
+make RPXlite_DW_NVRAM_config
+
+BTW,you can combine the above features together and get a workable u-boot to meet your need.
+For example,to get a 64MHZ && ENV_IS_IN_FLASH && LCD panel support u-boot,you can type:
+
+make RPXlite_DW_NVRAM_64_LCD_config
+make all
+
+So other combining make commands could be:
+
+make RPXlite_DW_NVRAM_64_config
+make RPXlite_DW_NVRAM_LCD_config
+make RPXlite_DW_64_LCD_config
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The boot process by "make RPXlite_DW_config" could be:
+
+U-Boot 1.1.1 (Jun  8 2004 - 11:16:30)
+
+CPU:   PPC823EZTnnB2 at 48 MHz: 16 kB I-Cache 8 kB D-Cache
+Board: RPXlite_DW
+DRAM:  64 MB
+FLASH: 16 MB
+*** Warning - bad CRC, using default environment
+
+In:    serial
+Out:   serial
+Err:   serial
+Net:   SCC ETHERNET
+u-boot>
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I'd like to extend my heartfelt gratitute to kind people for helping me work it out.
+I would particually thank Wolfgang Denk for his nice help.
+
+Enjoy,
