Second part of the patch.For the sake of unimplemented
in 4*8 AMD flash in CFI driver,I still use stand alone
FLASH driver.Also readme of this board is added!
Best regards,
Sam

+
+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_NVRAM/CFG_ENV_IS_IN_FLASH
+
+The default environment parameter is stored in NVRAM
because it doesn't have any special
+purpose for EP.Meanwhile,its operation is faster than
FLASH's.So I make FLASH 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 FLASH support,you may use the following build
command:
+
+make RPXlite_DW_FLASH_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_FLASH_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_FLASH_64_LCD_config
+make all
+
+So other combining make commands could be:
+
+make RPXlite_DW_FLASH_64_config
+make RPXlite_DW_FLASH_LCD_config
+make RPXlite_DW_64_LCD_config
+
+
+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,
