Eclair vs Donut (vs Froyo?)

Recently, focus on some issues on eMMC/SD deferred resume & retry mechanism.
More, one special SD card issue on Android volume daemon.

Here I got a new one about LK (little kernel) in Eclair, likes USBloader in Donut.
It might be for Qualcomm platform only.
LK is multi-thread and out of Android system code, it is independent for easily maintain.
USBloader is part of Android system code and single thread, faster than multiple one.

I am not sure is there any problem on LK, but I met some booting issue on that.
Just keep tracking the root cause.
I will use JTAG Debugging tool with TRACE32 for help soon.
Hope I could find out the cause ASAP.
