Why do we need a separate DRAM init code then?
I think it does. See dram_sun8i_a33.c . We used to use per-device dram code, but failed after allwinner uses libdram, then we worked on modifying H3 code. I think it's also possible to make H3 code capable of A33, but since our A33 code works well, should we do it? > > Thanks, > Maxime > > -- > Maxime Ripard, Free Electrons > Embedded Linux and Kernel engineering > http://free-electrons.com _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
