Now that Crust (SCP firmware) has support for H3, we need a FIT image to load it. H3 also needs to load a SoC-specific eGon blob to support CPU 0 hotplug. Let's first enable FIT support before adding extra firmware. Update the binman description to work on either 32-bit or 64-bit SoCs: - Make BL31 optional, since it is not used on 32-bit SoCs (though BL32 may be used in the future). - Explicitly set the minimum offset of the FIT to 32 KiB, since SPL on some boards is still only 24 KiB large even with FIT support enabled. CONFIG_SPL_PAD_TO cannot be used because it is not defined for H616. FIT unlocks more features (signatures, multiple DTBs, etc.), so enable it by default. A10 (sun4i) only has 24 KiB of SRAM A1, so it needs SPL_FIT_IMAGE_TINY. For simplicity, enable that option everywhere. Cover-letter: sunxi: SPL FIT support for 32-bit sunxi SoCs 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.
