  • 39e857616   mx5: Mark lowlevel_init board-specific code ... Browse Code »

    The mx5 lowlevel_init.S contains board-specific code based on the reference
    design. Let's keep it since it avoids creating new lowlevel_init files and it
    may be used by many boards. But add a config to make it optional in order not to
    cause issues on boards not following this part of the reference design.

  • 9db1bfa11   ARM: MX51: PLL errata workaround ... Browse Code »

    This is a port of the official PLL errata workaround from Freescale to
    mainline u-boot.
    The PLL's in the i.MX51 processor can go out of lock due to a metastable
    condition in an analog flip-flop when used at high frequencies.
    This workaround implements an undocumented feature in the PLL (dither
    mode), which causes the effect of this failure to be much lower (in terms
    of frequency deviation), avoiding system failure, or at least decreasing
    the likelihood of system failure.
