Microzed issues

List

• UART

Description:
    UART register contents: timeout=0 rxfifo_level=56, should be timeout=10 rxfifo_level=56
    minicom prints 56 symbols at a time when rxfifo reaches its level.
    remembers all typed symbols
    sometimes the timeout register is set correctly
Possible reason:
    In driver .startup and .termios conflict?

• SSH terminal

Description:
    Freezes, lags but remembers all typed symbols
Possible reason:
    UART problem?

• RTC

    Too many messages when rtc is missing
Description:
    3x"hwclock: can't open '/dev/misc/rtc': No such file or directory" in boot log
Possible reason:
    driver
