Currently building U-Boot as the coreboot payload requires user to change the build configuration for a specific board during menuconfig process. This uses the board's native device tree to configure the hardware. For example, the device tree provides PCI address range for the PCI host controller and U-Boot will re-program all PCI devices' BAR to be within this range. In order to make sure we don't mess up the hardware, we should guarantee the range matches what coreboot programs the chipset. But we really should make the coreboot payload support easier. Just like EFI payload, we can create a generic coreboot payload for all x86 boards as well. The payload is configured to include as many generic drivers as possible. All stuff that touches low level initialization are not allowed as such is the coreboot's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.
