kernel compile time and boot time
I have two questions.
1) How to reduce the kernel compiling time.
It takes 20 minutes to cross-compile an arm-linux on my pc machine from make dep to make boot. Is there a simple way to change the Makefile, so it ignore the unnecessary staff?
If I increase my ram from 512MB to 1024MB, will it make a big help?
2) How long it taks to boot your embedded linux.
It takes 20 seconds for my arm-linux from the power-on to the shell prompt. Any tips for reduce the time?
Thank you in advanced.
