Acked-by: Arnd Bergmann This looks reasonable to me as well, in particular as the code only supports the two ppc44x virtex developer boards and no commercial products. It does raise a follow-up question about ppc40x though: is it time to retire all of it? The other ppc405 machines appear to have seen even fewer updates after the OpenBlockS 600 got added in 2011, so it's possible nobody is using them any more with modern kernels. I see that OpenWRT removed both ppc40x and ppc44x exactly a year ago after they had not been maintained for years. However, 44x (in its ppc476 incarnation) is clearly still is used through the fsp2 platform, and can not be deprecated at least until that is known to have stopped getting kernel updates. Arnd
