The patches are here [1], along M3N ULCB support, which I believe is broken thus far and so none of that is posted to the ML yet. I'll be fixing that at the end of month, once I have physical access to the board (and there's more stuff coming :) ) [1] https://github.com/marex/u-boot-sh/tree/m3nulcb-v1 > The mainline v5.0 device trees lack the reserved-memory node, so I > expect the errors will not show up with vanilla kernel and DTB. > FTR, the errors appear regardless of the value for U-Boot > CONFIG_ARCH_FIXUP_FDT_MEMORY (=n is the default). > I tried to play with different values of bootm_size (including the > recent https://patchwork.ozlabs.org/patch/1052012/), with no success. The reserved memory nodes are used for the FCNL, right ? If so, then we will have to deal with it somehow.
