config CACHE_FLUSH_WATCHDOG_THRESHOLD
int "Bytes to flush between WATCHDOG_RESET calls"
default 0
help
The flush_cache() function periodically, and by default for
every cache line, calls WATCHDOG_RESET(). When flushing a
large area, that may add a significant amount of
overhead. This option allows you to set a threshold for how
many bytes to flush between each WATCHDOG_RESET call.
