Thanks, that helps to understand what is u-boot.bin

However, it's still unclear (1) for what type of a chip the rest of binaries are, (2) how to disassemble them. And (3) what is the process of booting (the big picture).

I have some experience with PIC micro-controllers and soldering-related stuff. So, I hope, I'll be able to tell more after tools for disassembling kindle and serial/usb board arrive.

Update 1:
Interestingly, here is what binwalk says about bios.bin (original image):
