PS4, Line 2363: rom_base_address = 0xFFFFFFFF - ctx.rom_size + 1;
At most 16M gets mapped. which part of 32 or 64M flash is configurable. Comparing the efs and body location is just confusing. Can't just use which 16M part of a flash you want as location for body and efs as an input instead of using weird and incorrect memory mapping semantics?
