Create documentation on how FPGA boot sequence is done

Create the notes for how FPGA boots

This is so that we would know if we can use the FPGA as a part of bootloader integrity verification.

Goals

• Determine if FPGA lose their states when turned off.
• Get a better understanding of the boot flow for the FPGA. Might have to expand the scope to the entire board as the other microcontrollers may play a part in the boot sequence for the FPGA as well.

Deliverables

• New documentation on how an FPGA boots
• Answer the question if a programmed FPGA will keep its configuration after being turned off.

FPGAs are configured using a bitstream that is generated from compiling a design made in an HDL (like VHDL or Verilog) . The configuration representing the associated simulated hardware is stored in this bitstream. You could think of the bitstream like an executable of a program I guess. I might be wrong there, but I look forward to reading what you find! :) [you may take a class on this stuff called ECE410 later on]
