I'm talking about the bootstrap controller of the PPC. I suggest you take a
look at chapter "9. IIC Bootstrap Controller" for more information about this.

You don't need to call it. The PPC is reading these I2C bootstrap values
*before* starting the first lines of code from flash (if configured to use the
I2C bootstrapping).
So how are the strapping pins (UART0_DCD, UART0_DSR) configured in your custom
board?
Cheers,
Stefan
