Now I found that the system doesn't hang. It just decompresses the
image. It is unbearably slow. Do you guys know why it does so slowly?

Ping. What is the way to solve this?
I can NOT merge the CBFS to our code for a long time.

I update the code. It hangs at somewhere else. It seems to be what
Carl-Daniel said. Is there any workaround way to skip this and let do my
own job?

I am wondering if it is caused by CBFS and if it happens on other
board.
If any one can test it, I will be appreciating.
We have not solved the SMP startup printk locking yet. That explains the
mangled log messages.
Unless I'm mistaken we still decompress some parts multiple times
concurrently to the same address and that can crash the code.
Overlapping stack might also crash the code during lzma decompression.
Decompression of AP code should happen on the BSP or on exactly one AP,
but not on all APs.
