Thanks for following up on this. I ended up cherry-picking the patches into my branch. I like to keep my next based on rc2, and merging this would have pulled in everything up to rc7 into my branch. I don't think you were planning to merge this branch anywhere else, so it shouldn't make any difference, but let me know if it's a problem. It should appear here soon: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/log/?h=next cheers > Original v1 text follows below, from: > > https://lore.kernel.org/lkml/20210111082823.99562-1-paul.gortma...@windriver.com > > It would be nice to get this in and off our collective to-do list. > > Thanks, > Paul. > > --- > > In v2.6.27 (2008, 917f0af9e5a9) the sbc8260 support was implicitly > retired by not being carried forward through the ppc --> powerpc > device tree transition. > > Then, in v3.6 (2012, b048b4e17cbb) we retired the support for the > sbc8560 boards. > > Next, in v4.18 (2017, 3bc6cf5a86e5) we retired the support for the > 2006 vintage sbc834x boards. > > The sbc8548 and sbc8641d boards were maybe 1-2 years newer than the > sbc834x boards, but it is also 3+ years later, so it makes sense to > now retire them as well - which is what is done here. > > These two remaining WR boards were based on the Freescale MPC8548-CDS > and the MPC8641D-HPCN reference board implementations.
