* SYSRSTn Duration Counter Support
*
* Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
* When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
* The SYSRSTn duration counter is useful for implementing a manufacturer
* or factory reset. Upon a long reset assertion that is greater than a
* pre-configured environment variable value for sysrstdelay,
* The counter value is stored in the SYSRSTn Length Counter Register
* The counter is based on the 25-MHz reference clock (40ns)
* It is a 29-bit counter, yielding a maximum counting duration of
* 2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
* it remains at this value until counter reset is triggered by setting
* bit 31 of KW_REG_SYSRST_CNT
