Similar to the lzma-loader on our MIPS targets, the spi-loader acts as a second-stage loader that will then load and start the actual kernel. As the TL-WDR4900 uses SPI-NOR and the P1010 family does not have support for memory mapping of this type of flash, this loader needs to contain a basic driver for the FSL ESPI controller.
