- Define CONFIG_SYS_EXCEPTION_VECTORS_HIGH Define CONFIG_SYS_EXCEPTION_VECTORS_HIGH and remove specific initialization of CPU as high vector - Define CONFIG_DISPLAY_BOARDINFO and print board info - Add GPIO support - Define CONFIG_BOOT_PARAMS_P for all spear boards It also makes a few board_init calls redundant so remove them from the code - Enable OTG support - Enable SPI and SDMMC support - Enable USBH EHCI support - Disable caches explicitly - Keep ATAG interface for kernel booting The older kernel needs an ATAG interface to boot. The bootloader needs to pass the information in the form of ATAGS. Keep this ATAG interface with the new DT interface for kernel booting - Remove extraneous configurations
