This was originally part of my series adding SPL FIT support for 32-bit sunxi boards[0]. I hit this issue building a minimal SPI-only SPL for H5 that ended up fitting in 24 KiB. So it turns out this is a bug and not just a dependency for a new feature.
I followed Simon's second suggestion from his response to my original series[1].
