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.
Then you can switch to LCD and serial console freely just typing
Then you can switch to LCD and serial console freely just typing
'run lcd' or 'run ser'. They are only vaild when CONFIG_LCD was enabled.
To get a LCD support u-boot,you can do the following:

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 :
