    Generic udelay() with watchdog support · 3eb90bad
    Ingo van Lil authored
    According to the PPC reference implementation the udelay() function is
    responsible for resetting the watchdog timer as frequently as needed.
    Most other architectures do not meet that requirement, so long-running
    operations might result in a watchdog reset.
    
    This patch adds a generic udelay() function which takes care of
    resetting the watchdog before calling an architecture-specific
    __udelay().
