Yes but no other company that I'm aware of launches an MCU with alternate cores from different vendors - it's just a waste of an albeit quite small area of silicon. ARM have their big.LITTLE thing but that's already handled in TrustZone.I'm not convinced it's the Hazard3 cores which are the problem, just that the glitch applied to the OTP part allows them to become enabled. I am guessing that would probably have been the case no matter what the alternative cores were.
RPL only included the RISC-V cores because an employee had designed it as a 'homer' so they didn't have to pay a licence fee, but now it's probably going to cost them a fortune both in re-spin fees and lost sales whilst the chip is respun.
