Hi all,

I tried to ask for some help last week about the basics, but got no
responses in here, unfortunately:

http://lists.denx.de/pipermail/u-boot/2013-September/163875.html

I decided to give it one more go. My current question: if I have a working
u-boot for our board, and I only added the line below, can I build SPL that
it initializes everything correctly, like PLL, external DDR memory, etc?

#define CONFIG_SPL_TARGET  "u-boot-spl.bin"

...

Thank you in advance,
