Subject[PATCH 07/11] init: consolidate the GENERIC_CALIBRATE_DELAY symbol
Date
Add one definition to init/Kconfig and let the architectures select it
if supported. The only complication is xtensa, where it is a user
visible option - we introduce a xtensa-specific symbol instead to work
around this.
