IBL is designed as a two stage bootloader, the iblinit and the iblmain.
The iblinit does the PLL initialization and executes a PLL workaround code to get around a silicon bug in revision 1.0 chips and jumps back to Boot ROM for non I2C boot modes.
The ibl main is the main bootlaoder that does pulls ELF data from the boot device (NAND/NOR/TFTP ..) and launches it.
