But many of them just define BOOT_DEVICE_* macros. Those macros are used in the "switch (boot_device) { ... }" statement in common/spl/spl.c. So they should not be archtecture specific, but be described as a simpile enumeration. This commit merges most of arch/arm/include/asm/arch-*/spl.h into arch/arm/include/asm/spl.h. With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h will be merged, while I am not sure about OMAP and Exynos.

The SPL for Ventana does the following: - setup i2c and read the factory programmed EEPROM to obtain DRAM config and model for board-specific calibration data - configure DRAM per CPU/size/layout/devices/calibration - load u-boot.img from NAND and jump to it This allows for a single SPL+u-boot.img to replace the previous multiple boa configurations.
