Hm, can't add much to Xilinx ppc405/440 removal patch debate.=20 But as for the APM82181 with it's PPC464: The last time I checked was with 5.6-rc4, it worked fine on the APM82181 (a MyBook Live) device. I've made a "build your own powerpc debian sid" image thing that takes the latest kernel git and up-to-date packages from debian ports (they still make powerpc packages!):=20 . Though, this is small potatoes. There exists a much more popular project by Ewald Comhaire (CCed): that serves the largest userbase: I guess we should think about upstreaming the MyBook Live DTS. Problem here is that we deviated a bit from the canyonlands.dts/bluestone.dts structure by having a skeleton apm82181.dtsi with most of the SoC defintition and a wd-mybooklive.dts for the device. =20 Cheers, Christian
