This series makes the necessary changes so 32-bit sunxi SoCs can load additional device trees or firmware from SPL along with U-Boot proper.
There was no existing binman entry property that put the FIT at the right offset. The minimum offset is 32k, but this matches neither the SPL size (which is no more than 24k on some SoCs) nor the FIT alignment (which is 512 bytes in practice due to SPL size constraints). So instead of adding a new property, I fixed what is arguably a bug in the offset property -- though this strategy will not work if someone is intentionally creating overlapping entries.
