Must be calibrated for correct operation of delay loops.
You simply use a stop watch to measure the 100 second delay
then adjust CONFIG_BOARD_LOOPSPERMSEC until it is actually
is 100 seconds.
int "Delay loops per millisecond"
default 5000
---help---
Simple delay loops are used by some logic, especially during boot-up,
driver initialization. These delay loops must be calibrated for each
board in order to assure accurate timing by the delay loops.
config ARCH_CALIBRATION
bool "Calibrate delay loop"
default n
---help---
Enables some built in instrumentation that causes a 100 second delay
during boot-up. This 100 second delay serves no purpose other than it
allows you to calibratre BOARD_LOOPSPERMSEC. You simply use a stop
watch to measure the actual delay then adjust BOARD_LOOPSPERMSEC until
the actual delay is 100 seconds.
