I would say you want to hypothetically add a _felboot build target for the allwinner boards that instead of building out a regular CONFIG_SPL_FRAMEWORK (I hope!) SPL spits out just a very tiny one that does what you need for this use case. Having different builds for different SPL cases is a normal thing that we do on a few boards, but none are quite so drastically different sounding as this.
Yes the main SPL is using CONFIG_SPL_FRAMEWORK. But the low level board initialization is done in s_init (via lowlevel_init).
This other boot helper is basically only calling s_init() and then returns to the caller with the board now configured in a reasonable state allowing it to accept u-boot.bin to be uploaded into SDRAM.
