[U-Boot] [PATCH v2][repost] arm: Kirkwood: add SYSRSTn Duration Counter Support

I am sorry for previous post v2, pls ignore it, this is the right patch for the same
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 (> ${sysrstdleay} 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

It is similar with one difference- sysrstcmd is additionally gated with h/w trigger, Secondly it is not as known as bootcmd, so it is always better to throw some error message. This save some of developer's time and email exchanges :-)

Does it harm if we keep this info? It is just like "cpu name, speed etc". SysRST is a feature provided by h/w that we are supporting, It may help users who are willing to use this feature Any way it is gated by "sysrstdelay" So I think we must keep this print alive

Um... yes... agreed, but that's not actually so special. Consider for example the use of "altbootcmd" in connection with the boot count limit feature, or the "failbootcmd" which gets run in case of critical POST errors. None of these produce any such error messages. For consistency I recommend to remove this message here, too.
Secondly it is not as known as bootcmd, so it is always better to throw some error message. This save some of developer's time and email exchanges :-)
Well, for developers it may be useful during test - but it should not be present for regular users of the production version. Maybe you change it into a debug() ?

Does it harm if we keep this info?
Well, yes, it does. It adds output, which makes the boot process more noisy and addds to the boot time. And normally none of the end users will actually ever look at this information.
It is just like "cpu name, speed etc".
Well, this _is_ information which the end users regularly check and pay attention to.
SysRST is a feature provided by h/w that we are supporting, It may help users who are willing to use this feature Any way it is gated by "sysrstdelay" So I think we must keep this print alive
Really? What is the advantage for the enduser to know if he pressed the button for 5.1 or 5.3 seconds?
Please make it a debug().

What for? He can see the difference from different behaviour.
If you really feel you want to be verbose you can lard your definitions of bootcmd, altbootcmd, failbootcmd, sysrstcmd, etc. with any number of "echo" commands you like.
But please don't make the default output more verbose than really necessary.
