[RFC] Kernel 'boot cache' to reduce boot time

2010-08-31 Thread Andrew Murray
Hello, I have a suggestion for a kernel framework which aims to reduce boot time in embedded devices and would be interested in hearing your feedback. A large portion of kernel boot time is spent in driver probe functions often waiting for hardware for example calculating LPJ values or trying to
