The CONFIG_SPL_MAX_SIZE could be 0x27000 for i.MX8MM when SPL_TEXT_BASE set to 0x7E1000.

I wonder if there is any more explanation for the maximum size that can be used. According to the RM, the TCML and TCMU area has a total size of 256 KB. But it seems only 156 KB is usable for the SPL!?
Without binman to pack ddr firmware, ddr firmware will take 96KB so 4KB + 156KB + 96KB = 256KB. With binman enabled in the future, SPL_MAX_SIZE could be larger. With ddr firmware runtime on demand loading ,it will larger!!
Thanks for the explanation! That was the part I was missing. If you happen to respin this, it would be nice to have this explanation in the commit message.
