early stage debugging on a real product

[Andy Shevchenko]

Hi!

I have been debugging U-Boot on a product (Android-based) device (*)
which is not yet supported by U-Boot. It's x86 based.

I have stumbled over the couple of things:
1/ it required me to enable TIMER_EARLY and by code analysing I can
tell that DM loop fails by some reason
2/ it hangs
   reserve_uboot,
   reserve_malloc,
   reserve_board,
   ...here...

My suspicion that fastboot does bad things to it (overwritten memory)
or something I have missed. Any ideas what to try / where to look into
besides the above which I'm on?

(*) Only I can get is just an approximate place where the code is
stuck / hangs. And it's time consuming...
