Summary

And thus has a limited range of supported baud rates. Also add that
setting BOOT_BOOT0_COMCONSOLE_SPEED=0 will leave it unchanged which
sometimes can give you 115200 if the BIOS initialized things outside of
the normal BIOS baud rates (which many x86 enbedded-targetted boards
do).

I think you could drop the "In addition" tho, just if BOOT_BOOT0_COMCONSOLE_SPEED=0, then ...

Perhaps only use "severely limited' once? :)
