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 Signed-off-by: Prafulla Wadaskar --- include/asm-arm/arch-kirkwood/cpu.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include') diff --git a/include/asm-arm/arch-kirkwood/cpu.h b/include/asm-arm/arch-kirkwood/cpu.h index d1440af..b3022a3 100644 --- a/include/asm-arm/arch-kirkwood/cpu.h +++ b/include/asm-arm/arch-kirkwood/cpu.h @@ -36,6 +36,8 @@ ((_x ?
