Hi, We currently have several boards based around the 88f6281 (kirkwood) ARM CPU. The boards all share a kernel image (currently 3.16 based but we're in the process of moving to 4.3). We use the machine id (and some other eeprom type information) to distinguish the boards. We'd like to move to a device tree based model but we're restricted in that updating the bootloaders to a DT-aware u-boot is impractical. CONFIG_ARM_APPENDED_DTB allows us to append a device tree but we still need to account for the differences between the boards. Is it possible to append several device trees and have the correct one selected based on mach-id? One alternative would be to have a lowest common denominator device tree and platform_data style initializations for the rest (which would kind of defeat the purpose of having a device tree). Or we could have a superset device tree with the nodes disabled and install fixups to enable them based on mach-id. Has anyone faced a similar situation?
