Up until now this has been considered the work of the payload. The existing ARM platforms supported in coreboot use SPI ROM to store the firmware.

In a generic sense, ARM support is working quite well. We've used it on a few different SoCs already, not just in the Exynos family. Most of that code is quite simple and portable.
If you're referring to the relatively few boards we support, that's another matter.
