Hi all,
I tried to ask for some help last week about the basics, but got no

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"
