Error in the RM0090 Rev21

Hi, I don't know where to post this message.

There's an error in the RM0090 Rev21 reference manual, page 121: "bit 15 of the PWR_CR register" should be "bit 14 of the PWR_CR register".

And most importantly, the debugger doesn't have bit 14 (VOS) of the PWR_CR register. I'm using an STM32F407ZET. I downloaded the archive https://www.st.com/resource/en/svd/stm32f4-svd.zip, and this bit is indeed missing from the STM32F407.svd file!

Please email whoever needs this information, and have them fix it.
