1. Stack setup for ARM supervisor mode
2. External Clock Detection
3. Switch Master Clock on Main Oscillator
4. C variable initialization
5. Main oscillator frequency detection
6. PLL setup: PLLB is initialized to generate a 48 MHz clock necessary to use the USB
7. Initialization of the DBGU serial port (115200 bauds, 8, N, 1)
8. Enable the User Reset
9. Jump to SD Card Boot sequence. If SD Card Boot succeeds, perform a remap and
10. Jump to NAND Flash Boot sequence. If NAND Flash Boot succeeds, perform a remap
11. Jump to DataFlash Boot sequence through NPCS0. If DataFlash Boot succeeds, per-
12. Activation of the Instruction Cache
