It boots anyway because with CONFIG_ARM_ATAG_DTB_COMPAT the ATAG_MEM from U-Boot overrides this node, but without it the kernel takes 512 MiB at face value: the upper half aliases the lower one (0x50100000 reads back what is at 0x40100000), CMA lands at 0x59800000, and it oopses in refill_objects once ~300 MB are in use. pp@5da00000 is then outside RAM as well; the vendor kernel reserves the top 64 MiB, i.e. 0x4c000000 on 256 MiB. Does your unit really have 512 MiB? If both sizes exist, maybe leave the size to the boot loader or use the smaller one. > + macaddr_tag_1e: macaddr@1e { > + compatible = "mac-base"; > + reg = <0x1e 0x6>; > + #nvmem-cell-cells = <1>; > + }; As far as I can see nothing in mainline implements the cell index for "mac-base" here, so all five ports get the same address (f4:f6:47:0f:42:64 on mine, wan included). The tag partition also stores the WAN address as its own record at offset 0x36 (..:42:65 on my unit), so a plain second cell works without mac-base: macaddr_tag_36: macaddr@36 { reg = <0x36 0x6>; }; Agustin
