OpenFirmware界面的目的是什么

Question

browsing the kernel source and looking at some drivers i found some methods and structures named with the prefix 'of' (for example struct of_device and the method of_phy_connect). I think that the prefix means OpenFirmware. In particular a driver i'm interested in (ucc_geth) uses those functions...what is the purpose?

Answer 1

它们用于枚举/操纵使用OpenFirmware的系统（新世界Mac，OLPC XO系统等）上的设备。
