 To support the Platform better,I added LCD panel(NL6448BC20-08) function.
 For the convenience of debug, CONFIG_PERBOOT was supported. So you just
 perss ENTER if you want to get a serial console in boot downcounting.

+This is enough for kernel NFS test. But as debug process goes on, you would expect
 to save some time on environment variable setting and u-boot/kernel updating.
 So the default environment variable setting would become more complicated. Just like
 the one I did in include/configs/RPXlite_DW.h.
 
 Two u-boot commands, ku and uu, should be careful to use. They were designed to update
-kernel and u-boot image file respectively. You must tftp your image to default address 
+kernel and u-boot image file respectively. You must tftp your image to default address
 '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 :
