Those files provide the initial support of the SoC: * The I6500 CPU and GIC interrupt controller. * The OLB ("Other Logic Block") providing clocks, resets and pin controls. * One UART. * One GPIO controller. * Two SPI controllers, one in host mode and one in target mode. * One octoSPI flash controller. * Two I2C controllers.
