This basically allows a : Linux kernel to handle variants of a board without having to custom : compile Linux for each board. At the moment I think only powerpc-based : boards can be handled in this way. In the kernel.org kernel, this is correct. There's a fairly mature set of patches for ARM that brings many of the newer ARM boards into the FDT picture. There's some very immature MIPS patches flowing around as well. Warner
