bfb6d510e9 Kirkwood: Makefile cleanup- fixed ordering (cosmetic change)
As per coding guidlines, it is good to maintain proper ordering
in the makefiles.
This was missed during initial coding, corrected here.

This was discovered during orion5x code review
Thanks to Albert Aribaud for this.

3eb90bad65 Generic udelay() with watchdog support
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().

49d2cb4d61 arm: Kirkwood: add SYSRSTn Duration Counter Support
This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)

Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
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

Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.

for-ex.
setenv sysrst_cmd "echo starting factory reset;
		   nand erase 0xa0000 0x20000;
		   echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event
