Allwinner low-level emulator, used for debugging baremetal payloads. Currently only Allwinner A133 is supported, other Allwinner SoC's are unsupported.
I'm lazy, and this was easier than constantly testing my baremetal payloads on real hardware. I also could've implemented support for any Allwinner SoC I wanted to emulate into QEMU, but, I prefer emulating an SoC using the Unicorn framework, because it's simple.
