That should go below spi.h

This function seems to be common. Can you please (in a separate patch)
move it into a separate shared file and delete all the copies?
Ok

+ sdram_initialise();
How come TPL is setting up the DRAM? Shouldn't that be done in SPL?
Due to size issues i needed to move spl load to sdram (not sram) and
sdram
settings
should be done by code executed in SRAM or you get to hang a board.
What is the size limit on SRAM?
RK3066 has 64KB SRAM but bootrom only reads 1KB + 31KB.
That is not a very low limit. RK3288 uses SPL (and not TPL) and it has
the same limit. Can we not just drop the use of TPL?
I don't think rk3066 can drop TPL, because the bootrom for rk3066 is
very much like rk3188:
- bootrom read 1KB and run it, in purpose of get higher frequency;
- back to bootrom;
- bootrom continue read 31KB most and run it;
- back to bootrom if needed;
- boot rom read and run loader like uboot.
OK then it sounds like we will need TPL. Is that right Pawel?
We don't need tpl if i use early back to bootrom in start.S patch with
spl... but i didn't test it yet. If it will work i will drop the tpl. Is
that ok?
Thanks,

Thanks
