Ivan Grokhotkov 5a88f90a33 soc/rtc: warn if detected XTAL frequency does not match configured one ... Since 9a8c0392, XTAL frequency is set to 40MHz by default, and users of 26MHz boards need to select 26MHz manually. Most users are not aware of this change, and existing getting started guides do not mention that XTAL frequency needs to be set for some boards. So users are left with garbage output from UART without any clue what to check. This change adds a warning in case specific XTAL frequency was set, and it does not match automatically detected one. This should help users fix the issue.		2017-09-11 11:42:26 +08:00
