CONFIG_SPL_TEXT_BASE is what specifies the address to which the SPL is linked.
This is the address where the BootROM should place the SPL and jump to it's 
first instruction.

I don't think you explicitly need to hack linker scripts to add this section.

btw. Tom Rini has a different email address (@konsulko) now.

btw2. is there any way I can help you with hacking on the SPL please ?
