There is no explicit document mentioned this bug is fixed on R5500, but it's not mentioned on "VR Series 64-/32-Bit Microprocessor Programming Guide" [1] either, while some other hardware limitations are mentioned in that guide. Plus EMMA platform, which was removed form the kernel, doesn't have cpu-feature-overrides.h. This means that the platform was running with LLSC enabled. So I think this CPU is not affected.
