what is the booting target? I've done in the past on non optimised android < 30s from cold start to UI on arm926ejs with base Android < 30s on more complex and full feature Android on Cortex-A9 (5 MiB kernel) < 30s with optimised bootloader (barebox) > > == Related work == > * 0xlab survey - Shorten Device Boot Time for Automotive IVI and > Navigation Systems; Implement Checkpointing for Android; Android > Boot Time Optimization > * CELF Boot time page - http://elinux.org/Boot_Time > > == Scope == > * Leverage most powerful hw platforms (multicore Cortex-A15 SOCs, fast > storage, etc.) more powerfull hw does not mean shorter boot time to be able to comparare anything we need have similar hw feature as more driver you have to load means more time to boot.
