I looked at this, but I didn't see way to overlay in an SRAM section. Do you have an example of how to do this? Hi! Is it really needed at all in the first place ? Why ? Isn't this need to specify the SPL to be located in the sram section? I see other platforms doing the same thing, ie. zynq, sunxi. 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. Ah yes, I think I can make use of it now. btw. Tom Rini has a different email address (@konsulko) now. Right...saw it right after I sent out this series. btw2. is there any way I can help you with hacking on the SPL please ? Let me post a v3 within this week, and I would appreciate any help. Does posting the series to git repo help you to help me? Dinh ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
